The present invention relates to curable photochromic compositions which include an at least di-functional oxazoline functional material, an at least di-functional first carboxylic acid functional material, an optional second carboxylic acid functional material having at least three carboxylic acid groups, which optionally includes a carboxylic acid functional polymer, and a photochromic compound. The curable photochromic compositions have an equivalents ratio of oxazoline equivalents of the oxazoline functional material to a total carboxylic acid equivalents of the first and optional second carboxylic acid functional materials of from 0.5:1 to 10:1 when the second carboxylic acid functional material is not present, and from 0.5:1 to 3:1 when the second carboxylic acid functional material is present. The present invention, more particularly, relates to curable photochromic adhesive compositions, and curable photochromic coating compositions.

This invention relates to new organic compounds, including 2-(2-allyloxy-1-methylethyl)-2-oxazoline and 2-(vinylbenzyloxy-1-methylethyl)-2-oxazoline. Its method of preparation comprises condensing 2-(3-hydroxy-2-propyl)-2-oxazoline with allyl chloride and vinylbenzyl chloride, respectively, in a phase transfer process. The invention is also directed to a method of copolymerizing 2-ethyloxazoline with such compounds.
