The present application provides a polycarbonate-based coating resin composition having high adhesiveness, more specifically provides a polycarbonate resin composition that contains not less than 0.1 parts by mass of a polyisocyanate compound and 100 parts by mass of a terminal-modified polycarbonate resin (A) having a structural unit (2) and a terminal structure represented by structural formula (1). [In formula (1) and formula (2), R-R, X, Y, Z, and a are as described in the description.] 2. The polycarbonate resin composition according to claim 1 , wherein claim 1 , in Structural formula (1) above claim 1 , Z represents a single bond claim 1 , Ris a C1-C2 alkylene group claim 1 , and R-Rare hydrogen.3. The polycarbonate resin composition according to claim 1 , wherein claim 1 , in the structural unit (2) claim 1 , X is —O— claim 1 , —S— or a divalent group represented by either one of General formulae (3)-(4) above.5. The polycarbonate resin composition according to claim 1 , wherein the structural unit (2) is derived from a bisphenol compound.6. The polycarbonate resin composition according to claim 5 , wherein the bisphenol compound is selected from the group consisting of bisphenol A claim 5 , bisphenol AP claim 5 , bisphenol Z claim 5 , bisphenol CD claim 5 , bisphenol C claim 5 , bisphenol IOTD claim 5 , bisphenol IBTD claim 5 , bisphenol MIBK and bisphenol AF.7. The polycarbonate resin composition according to claim 1 , wherein the terminal structure represented by Structural formula (1) above is p-hydroxyphenethyl alcohol (PHEP).8. The polycarbonate resin composition according to claim 1 , wherein the terminal structure represented by Structural formula (1) is contained in an amount of not less than 0.5 mol % relative to the amount of the structural unit (2).9. The polycarbonate resin composition according to claim 1 , wherein the polyisocyanate compound is an isocyanate compound containing two or more isocyanate groups per molecule.10. The polycarbonate ...
