PURPOSE:To obtain the titled composition having an improved sticking property against a paper doubling and a high coefficient of static friction of a surface by incorporating an ethylenically unsatd. addition polymerizable compd., a film formable polymer soluble to or capable of swelling to an aqueous alkaline solution, an optical polymerization initiator, a higher fatty acid and/or a higher fatty acid amide as the main components and also a specific fine particle to the titled composition. CONSTITUTION:The photopolymerizable composition comprises the ethylenically unsatd. addition polymerizable compd. (A), the film formable polymer soluble to or capable of swelling to an alkaline aqueous solution (B), the optical polymerization initiator (C) and the higher fatty acid and/or the higher fatty acid amide (D) which is solid at an ordinary temp. The fine particles are mixed to the prescribed photopolymerizable composition in the amount of 0.1-50wt% on the weight basis of the prescribed composition. Said particle has the following properties, namely (1) the particle having <=500mum the mean particle size, (2) the insoluble particle having a hydrophobic property on the surface thereof, (3) the substantial white or colorless particle, (4) the particle having the optical transmission property and 1.3-1.7 the refractive index. Preferably, the usable amount of the component (A) is 5-50wt% said amount of the component (B) is 10-90wt% on the weight basis of the photopolymerizable composition. The weight ratio of the components (A) and (B) is (0.5/9.5)-(5/5), and said amount of the component (C) is 0.5-15wt% on the weight basis of said composition. |
