PURPOSE:To suppress coloration function by compounding a product obtained by adding alkylene oxide or styrene oxide to resin acid reducing alcohol to non-carbon copying paper made of electron accepting compound or solid acid. CONSTITUTION:A sensing paper on which a solid acid that accepts electron and is made from clay minerals such as acid clay, bentonite, etc. is applied and on which paper are applied colloid dyes consisting of coloration agents such as crystal violet lacton and Rhodamine anilino-lacton, etc. that are electron imparting compounded with sensitivity reducing agent that contains a product obtained by adding alkylene oxide or styrene oxide to resin acid reducing alcohol. The reducing alcohol is preferably resin alcohol. The obtained non-carbon copying paper has little bleed-out to unprinted portions due to the effect of reduced sensitivity agent. |
