Water-pressure transfer printing film
A water-pressure transfer printing film that achieves a smooth image surface on the transfer target by allowing print images such as photographs to be transferred without causing the image quality to degrade, wherein such water-pressure transfer printing film is characterized in that it has at least two layers including an ink-receiving layer and a base layer and that the base layer has a surface roughness Ra of 0.40 μm or less and gloss of 80 or more.
1. A water-pressure transfer printing film comprising at least two layers including an ink-receiving layer made of polyvinyl alcohol and a base layer, said ink-receiving layer being water-soluble or -swelling and adapted to be separated from the base layer in water-pressure transfer printing, wherein at least a surface of the base layer that contacts the ink-receiving layer has a surface roughness Ra of 0.14 μm or more but less than 0.40 μm, and gloss of 80 or more.
2. A water-pressure transfer printing film according to claim 1 , characterized in that a wet tension of the surface of the base layer is 30 to 46 mN/m.
