Abstract (en)
[origin: JPS6219486A] PURPOSE:To prevent the yellowing due to ultraviolet rays, the gas in the air, etc. and the disappearing and fading color of a coloration picture due to plasticizer or the like, by a method wherein cyclic monoterpene group and phenol group are condensated under acidic catalyst and the titled sheet is composed of multivalent metallized carboxyl denatured terpenephenol resin obtained therefrom. CONSTITUTION:Cyclic monoterpene group and phenol group are condensated under acidic catalyst. Both the multivalent metallized carboxy denatured terpenephenol resin obtained by multi-metallizing the product in which carboxyl group is conducted thereinto and the above-mentioned condensated product are applied on the base material such as paper or the like. Cyclic monoterpene group and phenol group can be condensated by dissolving phenol group with solvents such as aromatic hydrocarbon like benzene, toluene, xylene, etc. or dichloromethane, chloroform, etc., ether group, aromatic hydrocarbon, carbon dioxide, etc. and then, by adding acidic catalyst thereto and dripping cyclic monoterpene group thereto within a temperature range from room temperature to 70 deg.C.
