Method for preparing a primer composition and coated product |
摘要 |
<p>A method for preparing a primer composition adapted to form a polysiloxane hard film on a cured primer layer of the composition comprising processes [1] or [2]: the process [1] comprising the steps of (I) preparing a primer precursor containing a vinyl polymer having a hydrolysable silyl group and an organic UV absorbing group bonded at side chains thereof and silica fine particles dispersed in an organic solvent; (II) adding water to the primer precursor obtained in (I) for hydrolysis; and (III) adding a dehydrating agent to the composition containing the hydrolyzate obtained in (II) to remove moisture from the composition; or the process [2] comprising (IV) hydrolyzing a vinyl polymer having a hydrolysable silyl group and an organic UV absorbing group bonded at side chains thereof by addition of water thereto; (V) adding silica fine particles dispersed in an organic solvent to the resulting hydrolyzate obtained in (IV); and (VI) adding a dehydrating agent to the composition obtained in (V) to remove moisture from the composition.</p> |
