Title:
(METH)ACRYLIC ESTER COMPOUND AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2004/103949
Kind Code:
A1
Abstract:
A (meth)acrylic ester compound represented by the general formula (1): (wherein R11 represents a divalent aromatic group; R12 represents hydrogen or methyl; R13 represents aryl; R14 represents hydrogen or methyl; and X11 represents oxygen or sulfur); and a dental material containing the compound. The dental material and dental composition which each contains the compound represented by the general formula (1) are useful because they have excellent curability and combine transparency, suitability for roentgenography, and low polymerization shrinkage while retaining various properties required of dental materials (e.g., flexural strength). A polymerizable composition containing the (meth)acrylic ester compound represented by the general formula (1) can be polymerized and molded in a short time by photopolymerization. It gives a cured resin satisfactory in transparency, optical properties (refractive index and Abbe's number), heat resistance, mechanical properties, etc. Also provided is an optical part obtained by polymerizing the polymerizable composition.
