<p>PURPOSE:To surely prevent such trouble as erosion of a colored layer by a solvent and consequent generation of color blurring by using a cyclopentadiene resin as a main binder resin. CONSTITUTION:The binder resin is mainly formed of the cyclopentadiene resin. The cyclopentadiene resin to be used is obtainable by a method of thermally polymerizing a cyclopentadiene monomer alone such as cyclopentadiene or methylcyclopentadiene or the dimer, trimer or co-dimer thereof or the mixture composed thereof in accordance with the conventional method, or a method for thermally polymerizing a mixture composed of the cyclopentadiene monomer and the monomer copolymerizable therewith or by bringing unsatd. dicarboxylic anhydride, phenolic resin, etc., into reaction with the resin obtd. by such thermal polymn. The trouble such as generation of color blurring is thereby surely prevented.</p> |
