    摘要： Disclosed are a polyester binder resin for coating which is copolymerized with lactic acid or a compound derived therefrom and isosorbide, and thus has a high content of biomass-derived compounds, and exhibits superior coating hardness, contamination resistance, hydrolytic resistance, processability and the like, and a coating composition comprising the same. The polyester resin binder for coating is copolymerized with a diacid component, a diol component comprising 1 to 60 moles of isosorbide, with respect to a total diol component, and 1 to 50% by weight of lactic acid or a compound derived therefrom, with respect to the total amount of resin polymerization reactants, wherein the polyester resin binder for coating has a structure in which a diacid moiety derived from the diacid component, a diol moiety derived from the diol component, and a hydroxyl monoacid moiety derived from the lactic acid or a compound derived therefrom are repeated.

    摘要： A polyester resin which includes acid components having aromatic dibasic acid component and trivalent or higher acid component; alcohol components including aliphatic, aromatic or cycloaliphatic diol component, and trihydric or higher alcohol component; polyolefin polyol having 1,800 to 2,500 number average molecular weight and hydroxyl value of 40 to 55 KOHmg/g; and wax having melting point of 80 to 110, wherein the amount of the polyolefin polyol is 0.1 to 2 weight % and the amount of the wax is 0.5 to 15 weight % with respect to the total polyester resin. Also disclosed is a method for preparing polyester resin by (a) carrying out an esterification reaction or an ester exchange reaction with the acid components, the alcohol components, and the polyolefin polyol; and (b) carrying out a polycondensation reaction for reaction product of the esterification or ester exchange reaction in the presence of the wax.
