Title:
POLYESTER BINDER RESIN FOR COATING, AND COATING COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2012/138145
Kind Code:
A2
Abstract:
Disclosed are a polyester binder resin for coating, and a coating composition containing the same, wherein lactic acid or a compound derived therefrom and isosorbide are copolymerized, and thus the content of biomass-derived compounds is high and coating hardness, contamination resistance, hydrolysis resistance and processability are excellent. The polyester binder resin for coating is obtained by copolymerizing a dibasic acid component; a diol component containing 1-60 mol of isosorbide with respect to the total diol components; and 1-50 wt% of lactic acid or a compound derived therefrom with respect to the total resin polymerization reactants, and has the structure in which a dibasic moiety derived from the dibasic acid component, a diol moiety derived from the diol component, and a hydroxy monobasic acid moiety derived from said lactic acid or a compound derived therefrom are repeated.
