Patent ID: 8911869

Claim:
A transparent substrate, comprising: an inorganic glass; and a first resin layer placed on at least one side of the inorganic glass, wherein: the first resin layer contains a resin compound having repeating units represented by general formulae (1), (2), and (3); and no solvent crack occurs when a mixed solvent containing 20 wt % to 95 wt % of at least one kind of solvent selected from the group consisting of acetone, N-methylpyrrolidone, dimethyl sulfoxide, and N,N-dimethylformamide is brought into contact with the substrate: in the formula (1), R 1 represents a linear or branched alkyl group having 1 to 5 carbon atoms, R 2 represents a linear or branched alkyl group having 2 to 5 carbon atoms, and A 1 and A 2 each independently represent an oxygen atom, a single bond, or a linking group represented by a general formula (5); in the formula (2), X represents a substituted or unsubstituted arylene group having 6 to 18 carbon atoms, and A 3 and A 4 each independently represent at least one kind selected from linking groups represented by general formulae (4) to (8), and the A 3 and the A 4 are bonded to para positions or meta positions of X; in the formula (3), R 3 represents a methyl group, or a substituted or unsubstituted aryl group having 6 to 18 carbon atoms, and A 5 and A 6 each independently represent an oxygen atom, a single bond, or the linking group represented by the general formula (5); and the number of A 3 's and A 4 's bonded to the para positions is three or more times as large as the number of A 3 's and A 4 's bonded to the meta positions.
