  • Semi-cured product, cured product and method for producing these, optical component, curable resin composition, and compound
    Patent number: 9334352
    Abstract: A curable resin composition containing a compound of formula (1), a compound of formula (2) and a thermal- or photo-radical polymerization initiator is capable of producing a cured product having a low Abbe's number and capable of realizing burr reduction in molding the composition.
    Type: Grant
    Filed: March 25, 2015
    Date of Patent: May 10, 2016
    Assignee: FUJIFILM Corporation
    Inventors: Ayumi Someya, Masataka Yoshizawa, Tatsuhiko Obayashi, Hiroyuki Naitou
  • Semi-cured product, cured product and method of manufacturing same, optical component, curable resin composition
    Patent number: 9193817
    Abstract: A curable resin composition comprising a (meth)acrylate monomer having an aromatic ring, a non-conjugated vinylidene group-containing compound represented by the general formula below, and a thermal or a photo-radical polymerization initiator makes it possible to produce a cured product with minimized occurrence of burring during molding and high product yield after molding. The cured product has good heat coloration resistance and low Abbe's number. R11, R12, R15, and R16 represent a substituent and A represents an atomic group necessary for forming a cyclic structure.
    Type: Grant
