Abstract

A scenario-adaptable color-changing ink and a corresponding solar glass product are provided. The ink includes 7-30 parts by weight of photopolymer, 8-20 parts by weight of photoactive monomer, 1-5 parts by weight of photosensitizer, 30-55 parts by weight of weather-resistant resin, 1-10 parts by weight of curing agent, and 1-15 parts by weight of pearlescent pigment. The pearlescent pigment is at least one interference pearlescent pigments with weather-resistance, which has no color. Each sheet of the pearlescent pigment can be considered as a miniature prism which can break the white composite light into colorful monochromatic light, thus allow the coating of the printing ink to present a beautiful pearl luster and metallic luster. The pattern color which is visible by human is a result of overlaps and interferes of lights that the incident light is multiply reflected and refracted by the sheets of transparent pearlescent pigment.

Claims (12)

1. A scenario-adaptable color-changing ink,

wherein the ink comprises 7-30 parts by weight of at least one photopolymer, 8-20 parts by weight of at least one photoactive monomer, 1-5 parts by weight of at least one photosensitizer, 30-55 parts by weight of at least one weather-resistant resin, 1-10 parts by weight of at least one curing agent, 1-15 parts by weight of at least one pearlescent pigment, 0-3 parts by weight of at least one adhesion promoter, 0-3 parts by weight of at least one ultraviolet absorber, and 0-1 part by weight of at least one antifoaming agent,

wherein the at least one photopolymer is from a group consisting of organosilicon polyurethane acrylate, polybutadiene polyurethane acrylate, cyclic acrylated acrylate, and hydrophobic polyester polyurethane acrylate with 2-6 degrees of functionality,

wherein the at least one photoactive monomer is from a group consisting of isobornyl acrylate, isobornyl methacrylate, tetrahydrofurfuryl ethoxylate acrylate, 1,6-hexanediol diacrylate, neopentyl glycol propoxylate diacrylate, and tris(2-acryloyloxyethyl) isocyanurate,

wherein the at least one photosensitizer is from a group consisting of 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy-2-methyl-1-phenyl propan-1-one, and 2,4,6-trimethylbenzoyldiphenyl phosphine oxide,

wherein the at least one weather-resistant resin is from a group consisting of an amorphous resin, fluorocarbon resin and polysiloxane resin,

and wherein the at least one curing agent is from a group consisting of amino resin, polyisocyanate, and endcapped hexamethylene diisocyanate.

2. The scenario-adaptable color-changing ink according to claim 1 , wherein the at least one pearlescent pigment is from a group consisting of interference pearlescent pigments.

3. The scenario-adaptable color-changing ink according to claim 1 , wherein the at least one pearlescent pigment is from a group consisting of natural mica, synthetic mica and transparent glass substrate.

4. The scenario-adaptable color-changing ink according to claim 1 , wherein the at least one adhesion promoter is from a group consisting of phosphate acrylate, amino silane coupling agent, methacryloxy silane coupling agent, and epoxy silane coupling agent.

5. A solar glass product comprising a substrate, wherein the scenario-adaptable color-changing ink according to claim 1 is printed on the substrate.

6. The solar glass product according to claim 5 , wherein the substrate is a glass substrate.
