Image recording composition, image recording ink set and recording apparatus
View Patent ↗An image recording composition including a curable material that is cured upon application of an external stimulus, water-absorbing resin particles, and a nonionic surfactant.
1. A recording apparatus comprising;
an intermediate transfer member;
a supply unit which comprises a housing unit storing an image recording composition, and which supplies the image recording composition onto the intermediate transfer member, the image recording composition containing a curable material that is cured upon application of an external stimulus, water-absorbing resin particles, and a nonionic surfactant,
the curable material including silicone-modified acrylic resin and one selected from a group consisting of acryloyl morpholine, N,N-dimethylacrylamide, dipropyleneglycol diacrylate, citric acid, ethylene-oxide-modified trimethylolpropane triacrylate, and polyoxyethylene diacrylate,
the water-absorbing resin particles including a crosslinked sulfonic-acid-modified sodium polyacrylate, and
the nonionic surfactant being one selected from a group consisting of a polyoxyethylene-propylene block copolymer nonionic surfactant polypropylene oxide ethylene oxide copolymer and block polymer, a polyoxyethylene stearyl amine, a polyoxyethylene lauryl amine, and a polyoxyethylene alkyl amine,
the content of the curable material being from 5% to 90% by weight with respect to the total solid content of the image recording composition, the content of the water-absorbing resin particles being from 5% to 80% by weight with respect to the total amount of the image recording composition, and the content of the nonionic surfactant being from 0.01% to 20% by weight with respect to the total amount of the image recording composition;
an ejection unit that ejects an aqueous ink containing an aqueous solvent onto a curable layer formed from the image recording composition that has been supplied onto the intermediate transfer member;
a transfer unit that transfers the curable layer onto which the aqueous ink has been ejected to a recording medium; and
a stimulus application unit that applies a stimulus that cures the curable layer.
2. A recording apparatus comprising:
a supply unit which comprises a housing unit storing an image recording composition, and which supplies the image recording composition onto a recording medium, the image recording composition containing a curable material that is cured upon application of an external stimulus, water-absorbing resin particles, and a nonionic surfactant,
the curable material including silicone-modified acrylic resin and one selected from a group consisting of acryloyl morpholine, N,N-dimethylacrylamide, dipropyleneglycol diacrylate, citric acid, ethylene-oxide-modified trimethylolpropane triacrylate, and polyoxyethylene diacrylate,
the water-absorbing resin particles including a crosslinked sulfonic-acid-modified sodium polyacrylate, and
the nonionic surfactant being one selected from a group consisting of a polyoxyethylene-propylene block copolymer nonionic surfactant polypropylene oxide ethylene oxide copolymer and block polymer, a polyoxyethylene stearyl amine, a polyoxyethylene lauryl amine, and a polyoxyethylene alkyl amine,
the content of the curable material being from 5% to 90% by weight with respect to the total solid content of the image recording composition, the content of the water-absorbing resin particles being from 5% to 80% by weight with respect to the total amount of the image recording composition, and the content of the nonionic surfactant being from 0.01% to 20% by weight with respect to the total amount of the image recording composition;
an ejection unit that ejects an aqueous ink containing an aqueous solvent onto a curable layer formed from the image recording composition that has been supplied onto the recording medium; and
a stimulus application unit that applies a stimulus that cures the curable layer.
3. An image recording composition comprising: a curable material that is cured upon application of an external stimulus, water-absorbing resin particles, and a nonionic surfactant,
the curable material including silicone-modified acrylic resin and one selected from a group consisting of acryloyl morpholine, N,N-dimethylacrylarnide, dipropyleneglycol diacrylate, citric acid, ethylene-oxide-modified trimethylolpropane triacrylate, and polyoxyethylene diacrylate,
the water-absorbing resin particles including a crosslinked sulfonic-acid-modified sodium polyacrylate, and
the nonionic surfactant being one selected from a group consisting of a polyoxyethylene-propylene block copolymer nonionic surfactant polypropylene oxide ethylene oxide copolymer and block polymer, a polyoxyethylene stearyl amine, a polyoxyethylene lauryl amine, and a polyoxyethylene alkyl amine.
