A laser weldable PBT-series resin composition and a molded product thereof are provided, in which the composition is weldable uniformly and has high welding strength even when the composition comprises a polybutylene terephthalate (PBT) as a base. The laser weldable resin composition comprises 1 to 50 parts by weight of (B) an elastomer (such as a polystyrene-series thermoplastic elastomer or a polyester-series thermoplastic elastomer), 5 to 100 parts by weight of (C) a polycarbonate-series resin, 1 to 10 parts by weight of (D) a plasticizer (e.g., an aromatic polycarboxylic acid ester, and an acrylic plasticizer), and 0 to 100 parts by weight of (E) a filler or reinforcing agent (such as a glass fiber), relative to 100 parts by weight of (A) a polybutylene terephthalate-series resin (a homopolyester or a copolyester). The molded product prepared from the resin composition has a small light transmittance fluctuation range depending on sites to be irradiated of the molded product. Thus, the molded product can be bonded to a counter part article uniformly by a laser welding.

A method is disclosed for improving alkaline solution resistance of a thermoplastic resin by blending an aromatic polyvalent carboxylic acid ester into the thermoplastic resin. Preferably, 1 to 15 parts by mass of the aromatic polyvalent carboxylic acid ester are blended with respect to 100 parts by mass of the thermoplastic resin. Additionally, an aromatic polyvalent carboxylic acid ester can be used for improving alkaline solution resistance of a thermoplastic resin. An alkaline solution resistance improving agent is also disclosed for a thermoplastic resin, the alkaline solution resistance improving agent containing an aromatic polyvalent carboxylic acid ester.
