The present invention provides a polybutylene terephthalate resin film having excellent resistance to hydrolysis and excellent flame retardancy, which is particularly suited for use in a back sheet film for a solar cell module. The film comprises a composition containing a polybutylene terephthalate resin (A), a brominated flame retardant (B) having a bisphenol A skeleton in the main chain thereof, and an antimony compound (C). The bromine content of the brominated flame retardant (B) having the bisphenol A skeleton in the main chain thereof is 8-30 parts by weight per 100 parts by weight of the polybutylene terephthalate resin (A), and the VTM flame retardancy of the film according to UL94 is VTM-0.

Polybutylene terephthalate resin film

In order to be halogen free and to be able to exert excellent solder heat resistance, electroless gold plating resistance, moisture resistance and resistance to electrode corrosion at a high sensitivity, a curable resin composition contains a curable resin (A) derived from a compound having a structure represented by general formula (1), and a layered double hydroxide (B). The curable resin composition and the dry film thereof can be advantageously used for the formation of a prepreg or a cured coating film such as a solder resist for a printed circuit board or a flexible printed circuit board. (In formula (1), R1 represents a polyhydric alcohol derivative having a valency of (m+l); m and n represent an integer of 1 or more and less than 10, 1 being an integer of 0 or at least 1; R2 represents CH2, C2H4, C3H6, C4H8 or a substituted or non-substituted aromatic ring; and R3 represents a substituted or non-substituted aromatic ring.)

Curable resin composition, dry film thereof, cured product of said curable resin composition, and printed circuit board using same

PURPOSE: To provide the subject composition composed of a thermoplastic polyester resin, a halogenated bisphenol A type resin, a hydrotalcite and a phosphoric acid ester, excellent in moldability and remarkably excellent in moisture resistance. CONSTITUTION: The objective composition contains (A) a thermoplastic polyester resin (preferably polyethylene terephthalate or polybutylene terephthalate), (B) a halogenated bisphenol A type resin (preferably having 1800 to 7000 epoxy equivalent), (C) an antimony compound (preferably antimony trioxide), (D) a hydrotalcite compound (preferably a compound of the formula) and (E) a phosphoric acid triester (preferably triphenyl phosphate, etc.). This composition is prepared recommendably by uniformly blending the components (A) to (E), subsequently melt kneading the resultant mixture at ≥ the melting point of the component (A) using a single- or multi-head extruder and then cutting the melt kneaded material into pellets using a cutter.

Thermoplastic flame-retardant polyester resin composition

PROBLEM TO BE SOLVED: To provide a polycarbonate resin molded product having high durability related to high bonding strength and airtightness when used as a permeable resin material being a polycarbonate resin. SOLUTION: The resin molded product is constituted by superposing two kinds of resin materials one upon another and melting the contact surfaces of two kinds of the resin materials by irradiating them with a laser beam which is used as a heating source, from one side to weld and bond the resin materials. The resin material on the side irradiated with the laser beam is polycarbonate (B) and the resin material on the side superposed on the irradiated resin material comprises a resin composition composed of polyarylene sulfide (A) polycarbonate (B), a thermoplastic elastomer (C) and an absorbent (D).
