The present invention provides laminated iron having excellent printability and a preparation method therefor. The laminated iron is prepared by using a mode of performing thermal-compounding on a polyester thin film having a durable and high surface tension force and a steel plate, wherein the polyester thin film is prepared by copolymerizing terephthalic acid, isophthalic acid, ethylene glycol and a fourth component and then bidirectionally stretching a co-polymer; a feeding mole ratio is that terephthalic acid:isophthalic acid:ethylene glycol:a fourth component=(135-165):(148-194):(11-15):(0.01-12); the fourth component is selected from one or more of isophthalic-5-sulfonate, 1,4-cyclohexane dimethanol, neo-pentanediol and trimellitic acid; and 800-2000 ppm of SiO.sub.2 in parts by mass is added to a copolymerized polyester by using a mode of in-situ polymerization. The laminated iron has excellent printability and satisfies usage requirements of packaging containers for food, beverage and the like.

The polyester copolymer according to the present disclosure is excellent in processability, particularly in shear thinning characteristics, and thus can be applied to the production of various transparent containers by an EBM process.

Disclosed in the present invention is a semiaromatic polyester, a preparation method and application thereof. Having a specific segment length and carboxyl group content, the semiaromatic polyester provides a balance of degradation rate and mechanical properties, compared with known semiaromatic polyesters. The 30-day weight retention of the semiaromatic polyester obtained in the present invention may be contained to from 45 to 70%.

A thermosetting coating composition includes a hydroxyl group-containing resin, a curing agent, a phosphazene compound, and a solvent. The curing agent is a polyisocyanate curing agent and/or a blocked polyisocyanate curing agent.

The present invention provides a composition having a sufficiently satisfying level of processability, curability, retort resistance or heat resistance, and abrasion resistance. The present invention relates to a composition containing: a solvent; thermoplastic resin (A) particles undissolved in the solvent; and a thermoplastic resin (B) dissolved in the solvent.

Use of a coating composition on a chromium free tinplate substrate, the coating composition comprising: a polyester material, and benzoguanamine or a derivative thereof,
wherein the coating composition is substantially free of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE).
