Abstract
Disclosed is Printing paper which incorporates a sheet substrate and a dye-receiving layer wherein the dye-receiving layer contains a vinylphenolic resin and a dyeable resin or contains a polymer of a vinylphenolic resin, a butyral resin and a poly-functional isocyanate. The printing paper is used in thermal sublimation transfer recording and gives an image with improved storing characteristics in terms of the light resistance, dark fading resistance, sebum resistance, plasticizer resistance, etc.
Claims4
A printing sheet comprising:
- a sheet substrate having a surface;
- and
- a dye-receiving layer disposed on said surface, said dye-receiving layer being a cross-linked coating obtained by curing a coating composition consisting essentially of:
- about 100 parts by weight of a butyral resin;
- about 1 to 100 parts by weight, based on 100 parts by weight butyral resin, of a vinylphenolic resin selected from homopolymers and copolymers of m-vinylphenol or p-vinylphenol;
- about 1 to 50 parts by weight, based on 100 parts by weight of said butyral resin and said vinylphenolic resin combined, of at least one polyisocyanate compound;
- and
- optionally, at least on additive selected from the group consisting of:
- solvents, plasticizers, whitening agents, pigments, UV absorbers, light stabilizers, antioxidants, surface-improving agents, releasing agents and antistatic agents.
