Summary:PURPOSE:To obtain a transparentizing treatment agent for paper, suitably used for partly or wholly transparentizing an opaque paper such as wood-free paper. CONSTITUTION:This transparentizing treatment agent for paper characteristically contains, as the active component, an aqueous polymer prepared by copolymerizing a monomer mixture containing (1) 5 to 95wt.% carboxylic group- containing ethylenic unsaturated monomer and (2) 95 to 5wt.% one or more kinds of monomers selected from styrenes and (meth)acrylic acid esters and neutralizing the resultant copolymer of <=2000 molecular weight and 60-550 mgKOH/g acid value with a basic compound. The transparentizing treatment agent can uniformly transparentize a part or whole of an opaque paper such as generally used wood-free paper at low cost. In addition, the resultant transparentized paper is excellent in blocking resistance at the surface, free from reduction of strength and excellent in dimensional stability.
