摘要： The hard coat layer-forming composition of this invention includes (A) composite oxide fine particles with a mean particle diameter of 1 to 200 nm, containing titanium, tin and optionally silicon, and with a rutile-type crystal structure, (B) an organosilicon compound represented by the formula R 1 a R 2 b Si(OR 3 ) 4-(a+b) and/or a hydrolyzate thereof, and (C) a cyanamide derivative compound. A hard coat layer formed from the composition not only is excellent in transparency, scratch resistance, adhesion property, weathering resistance, impact resistance, etc. but also can enjoy no coloration or little coloration, particularly in bluing or yellowing, upon exposure to or irradiation with ultraviolet rays, even if an antireflection film is provided.

摘要： The composite polymer of the invention is obtained by reacting (a) an elastomer having a carboxyl group with (b) metal oxide fine particles each having an epoxy ring-containing group on the particle surface. A thermally cured product of the composite polymer of the invention is a material favorable for forming a primer layer which has not only high transparency but also excellent adhesion to a hard coat layer and is excellent also in scratch resistance, heat resistance, weathering resistance, dyeing property, impact resistance and the like. An article such as an optical article whose primer layer comprises the thermally cured product of the composite polymer has high transparency and is excellent also in heat resistance.
