Title:
HIGH-MOLECULAR WEIGHT KETONE RESIN AND MOLDING PRODUCT, FILM AND OPTICAL FILM COMPOSED OF THE RESIN
Document Type and Number:
Japanese Patent JP2009249611
Kind Code:
A
Abstract:
To solve such problems that evaporation and deposition of various organic compounds, especially low-molecular weight components generated from coatings used occur, because a ketone resin suitably used as a modifier for coatings has a low molecular wight.
A high-molecular weight ketone resin is characterized in that the weight average molecular weight is 5,000-300,000 in the ketone resin obtained from a ketone and an aldehyde. The high-molecular weight ketone resin can be provided by using a heterocyclic amine having an amidine structure and can be suitably used as a molding product and a film.
