Abstract
A polyester ether containing in its main chain the moiety represented by the formula: --R.sub.2 OArR.sub.3 COO-- wherein Ar is an arylene group, R.sub.2 is an alkylene group or an oxaalkylene group, and R.sub.3 is a vinylene group, a butadienylene group or a vinylene or a butadienylene group substituted by one or more groups containing not more than 6 carbon atoms. A light-sensitive composition containing the above polyester ether is also disclosed.

A polyester ether having high molecular weight and film or fiber forming properties containing in its main chain the moiety represented by the formula:
- --R.sub.2 OArR.sub.3 COO--
- wherein Ar is arylene, R.sub.2 is alkylene or oxaalkylene and R.sub.3 is vinylene, butadienylene, or vinylene or butadienylene substituted by a group containing 6 or less carbon atoms.
A light-sensitive material comprising a support having thereon a layer comprising a polyester ether having high molecular weight and film or fiber-forming properties containing in its main chain the moiety represented by the formula:
- --R.sub.2 OArR.sub.3 COO--
- wherein Ar is arylene, R.sub.2 is alkylene or oxaalkylene and R.sub.3 is vinylene, butadienylene, or vinylene or butadienylene substituted by a group containing 6 or less carbon atoms, and an effective amount of a sensitizing agent to render the composition light-sensitive.
