PURPOSE:To provide the titled coating agent having favorable dyeable property, color forming property, clearness or the like and capable of providing a color forming material for color copying or the like, wherein an active ray hardenable resin, a specified phosphoric acid ester monomer and an amine compound are mixed with each other. CONSTITUTION:The desired coating material is obtained by mixing (A) an active ray hardenable resin, preferably, a mixture of a polymer with a monomer and/or oligomer which has at least 1.5 polymerizable groups or epoxy groups per molecule, (B) a phosphoric acid ester monomer of formula I , wherein at least one of groups X is CH2C(R1)CO(OR2)nO-, wherein R1 is H or CH3, R2 is 1-10C alkylene, and n is 0-10, each of the rest of the groups X being OH, and (C) an amine compound of formula II, wherein at least one of groups Y is H(OR3)m-, wherein R3 is 1-10C alkylene, and m is 1-10, each of the rest of the groups Y being H or 1-20C alkyl. The coating agent is preferably applied to a polyester film, and is hardened by irradiating with UV rays having a wavelength of 100- 800nm to obtain a color forming material. |
