摘要:
Provided are a silicon-containing resin composition with which it is possible to form a silica-based coating film in which generation of cracks is minimized, a method for forming a silica-based coating film using the silicon-containing resin composition, and a crack-free silica-based coating film formed using the silicon-containing resin composition. A silicon-containing resin composition including (A) a silicon-containing resin and (S) a solvent, wherein one or more selected from siloxane resins and polysilanes is used as the (A) silicon-containing resin, and the (S) solvent contains a cycloalkyl acetate having a specific structure. Cyclohexyl acetate is preferably used as the cycloalkyl acetate.

Provided are: a transparent body production method that uses a novel vinyl group-containing compound; and a transparent body obtained by this production method. This transparent body production method includes subjecting a vinyl group-containing compound that is represented by formula (1) to heating at a temperature equal to or greater than the melting point of said compound. In formula (1), each of W 1 and W 2 is the group represented by formula (2) (in the formula, the ring Z is an aromatic hydrocarbon ring, X is a single bond or a group represented by -S-, R 1 is a single bond or an alkylene group having 1-4 carbon atoms, R 2 is a specific substituent such as a monovalent hydrocarbon group, and m is an integer of 0 or higher), the group represented by formula (4) (in the formula, the ring Z, X, R 1 , R 2 , and m are as indicated above), a hydroxyl group, or an (meth)acryloyloxy group, each of the ring Y 1 and the ring Y 2 is an aromatic hydrocarbon ring, R is a single bond or a specific divalent group, each of R 3a and R 3b is a cyano group, a halogen group, or a monovalent hydrocarbon group, and each of n1 and n2 is an integer of 0-4.
