程度の量であれば含まれていてもよい。The polycarbonate resin used in the present invention is obtained by reacting a dihydric phenol and a carbonate precursor by a solution method or a melting method. The dihydric phenol used here is 2,2-bis (4-hydroxyphenyl) propane [commonly called bisphenol A], but a part of it may be replaced with another dihydric phenol.
Other dihydric phenols include, for example, 1,1-bis (4
-Hydroxyphenyl) ethane, 1,1-bis (4-hydroxyphenyl) cyclohexane, 2,2-bis (4
-Hydroxy-3,5-dimethylphenyl) propane,
2,2-bis (4-hydroxy-3-methylphenyl)
Examples thereof include propane, bis (4-hydroxyphenyl) sulfide, bis (4-hydroxyphenyl) sulfone and the like. Examples of the carbonate precursor include carbonyl halide, carbonyl ester, haloformate and the like, and specific examples include phosgene, diphenyl carbonate, dihaloformate of bisphenol A and the like. In producing the polycarbonate resin, an appropriate molecular weight modifier, a catalyst for accelerating the reaction, a branching agent for improving the processability and the like can be used if necessary. Also,
It is preferable to remove impurities in the produced polycarbonate resin by washing or the like, but the polycarbonate resin may be contained in an amount not causing a problem depending on the use.

A mixture of these may also be used. The amount of the ester added is 0.05 to 1.0 part by weight based on 100 parts by weight of the polycarbonate resin. If the amount is less than 0.05 parts by weight, it is difficult to obtain a sufficient effect of improving the stacking property, and if the amount is more than 1.0 parts by weight, the heat resistance during molding is deteriorated.
