Title:
CURE DEGREE EVALUATION METHOD, CURE DEGREE EVALUATION SHEET AND CURE DEGREE EVALUATION SYSTEM FOR ACTIVE ENERGY RAY-CURABLE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2010/098010
Kind Code:
A1
Abstract:
Disclosed is a cure degree evaluation method for evaluating the cure degree of an active energy ray-curable resin composition quantitatively, conveniently and with high accuracy. Also disclosed is a cure degree confirmation sheet for use in the cure degree evaluation method. Further disclosed is a cure degree evaluation system. Specifically disclosed is a cure degree evaluation method for an active energy ray-curable resin composition, which is a method for evaluating the cure degree of the active energy ray-curable resin composition. The method comprises the steps of: irradiating the active energy ray-curable resin composition with an active energy ray; and evaluating the cure degree of the active energy ray-curable resin composition based on the color of the active energy ray-curable resin composition, wherein the active energy ray-curable resin composition comprises at least a radically polymerizable composition, a leuco dye and a radical polymerization initiator.
