A method for determining quality of photocurable compositions by the change of the compostion's color during photocuring

摘要

The present invention relates to a process method of changing the color before and after curing when photocuring of the photocurable resin composition and, via the color change before and after such curing, which control the quality of the photocurable resin. Method for changing the curing before or after the color according to the present invention is photo-curable urethane-modified (meth) acrylate, carbonate group introduced into the urethane-modified (meth) using acrylic irreversible photochromic dye or a reversible photochromic dye in the acrylate resins to be the irreversible condition that contains, and how to control the quality of the photocurable resin through the curing before or after the color change according to the invention to determine the extent of cure of the abnormality or the resin of the hardening equipment of only the electrode protective material color change upon coating in the module process of LCD, etc. able to be characterized in that given the dramatic benefits in quality control. Existing optical path when applying the technique of the present invention to the chemical electrode protective moisture-proof insulation coating curing speed, adhesion, such as various physical properties by the concentration of color and color changes according to the extent of cure while maintaining the same level to determine the quality control luminous enemy We have been working together as well as the convenience of an effect, such as the appearance of hiding power granted. Method for changing the curing before or after the color upon photocuring of the photocurable resin composition according to the invention and, through these cured before or after the color change method for managing the quality of the photocurable resin is a liquid crystal display device, plasma display device, an organic light-emitting diode a flat panel display, such as electrode protective agents, may be used in the field of moisture-proof protective agent such as a condenser of the electronics.
