Polycarbonate resin composition

A resin solution comprising a polycarbonate resin composition and a nonhalogenated organic solvent, wherein at least a part of the polycarbonate resin composition is crosslinked, wherein the polycarbonate resin composition comprising:

• 100 parts by mass of a terminal-modified polycarbonate resin (A) having a terminal structure represented by structural formula (1) below and a structural unit (2) below;
• and
• not less than 0.1 parts by mass of a polyisocyanate compound,
• (in formula (1),
• R1 represents an optionally substituted C1-C20 alkylene group or C2-C20 alkenylene group,
• R2 and R3 each independently represent hydrogen, a C1-C20 alkyl group, a C1-C10 alkoxy group or a C6-C12 aryl group,
• Z represents an ether bond, a carbonyl group, an ester bond or a single bond,
• a is an integer of 1-3, and
• Y represents an ether bond or an ester group),
• (in formula (2),
• R4-R7 each independently represent hydrogen, fluorine, chlorine, bromine, iodine, or an optionally substituted C1-C20 alkyl group, C6-C12 aryl group, C2-C12 alkenyl group, C1-C5 alkoxy group or C7-C17 aralkyl group, and
• X is —O—, —S—, —SO—, —SO2—, —CO— or a divalent group represented by any of general formulae (4)-(6), or (8) below)
• in general formulae (4)-(6) and (8),
• R18 and R19 each independently represent hydrogen, a halogen, an optionally substituted C1-C20 alkyl group, an optionally substituted C1-C5 alkoxy group, an optionally substituted C6-C12 aryl group, an optionally substituted C7-C17 aralkyl group or an optionally substituted C2-C15 alkenyl group, or
• R18 and R19 bind to each other to form a C3-C20 carbocyclic ring or a C1-C20 heterocyclic ring,
• R20 is an optionally substituted C1-C9 alkylene group,
• c represents an integer of 0-20, and
• d represents an integer of 1-500);
• wherein the terminal structure represented by structural formula (1) is contained in an amount of 0.5 mol % to 8 mol % relative to the amount of the structural unit (2).
