The present invention provides a polycarbonate resin composition which is capable of maintaining favorable fluidity during molding, inhibiting a bleed-out phenomenon after molding, and further producing molding products with high transparency. Specifically, the polycarbonate resin composition comprises: an aromatic polycarbonate resin; and 0.01 to 1.0 parts by mass of a fatty acid compound relative to 100 parts by mass of the aromatic polycarbonate resin, the fatty acid compound containing at least one selected from the group consisting of fatty acid esters and fatty acid amides. The fatty acid compound has an average molecular weight of 800 to 5000. The fatty acid compound contains 10 to 80% by mass of an unsaturated fatty acid compound relative to the total mass of the fatty acid compound.

Polycarbonate resin composition

Disclosed is an aqueous binder for an inorganic-fiber heat-insulating sound-absorbing member, comprising a polycarboxylic acid and a crosslinking agent for the polycarboxylic acid, in which the polycarboxylic acid comprises a polycarboxylic acid having a weight average molecular weight of 1000 to 20000 and an acid value of 500 to 900 mgKOH/g; the crosslinking agent comprises a branched polyethyleneimine having a weight average molecular weight of 300 to 2000, and an alkanolamine having a lower molecular weight than the polyethyleneimine and an alcohol valence of 2 or less; the ratio of the total mole of a hydroxyl group, an amino group and an imino group in the crosslinking agent relative to the mole of a carboxy group in the polycarboxylic acid is 0.30 to 0.75; and the ratio of the total mole of the amino group and imino group in the crosslinking agent relative to the total mole of the hydroxyl group, amino group and imino group in the crosslinking agent is 0.34 to 0.80.
