摘要： PROBLEM TO BE SOLVED: To provide a primer composition to form a protective coating without weak points such as cracking, debonding and yellowing, for a long period of time, and excellent in weather resistance, and to provide a coated article using the composition. SOLUTION: This primer composition for a polysiloxane hard coating comprises (A) a vinyl polymer having a hydrolyzable silyl group and/or SiOH group and an organic UV absorbing group bonded to its side chain, and (B) fine silica particles dispersed in an organic solvent, the primer layer formed after coating and curing has a coefficient of linear expansion of ≤150×10 -6 /°C. The primer layer formed in such a manner has greatly improved lightfastness and inhibits the loss of a UV absorbing agent on standing. An organic-inorganic composite formed by siloxane crosslinking reduces the coefficient of linear expansion, becomes a binder excellent in weather resistance and thus imparts a UV absorbing protective coating superior in water resistance, solvent resistance and light fastness. The primer composition coated on a product with inferior weather resistance and cured controls decoloration and deterioration of the product, and imparts good weather resistance.
