Abstract
In accordance with the present invention, there are provided high performance, photoimageable resin compositions for flexographic printing, having excellent physical properties, e.g., resilience, hardness, toughness, and the like, as well as increased rates of cure upon exposure to radiation. In a further aspect of the invention, there are provided printing plates prepared employing invention compositions, wherein said printing plates are characterized as having excellent exposure sensitivity, the capability of rapidly curing upon exposure, excellent retention of fine details, and excellent colorloss performance. Moreover, printing plates prepared employing invention compositions have good flexibility, excellent washout properties, and retain such properties over extended periods of storage. In another aspect of the invention, there are provided methods for the preparation of formulations comprising said compositions and methods for use thereof.
