  • Patent number: 10030023
    Abstract: The invention provides a mercaptoalkylglycoluril represented by the general formula (I): wherein R1 and R2 each independently represent a hydrogen atom, a lower alkyl group, or a phenyl group; R3, R4, and R5 each independently represent a hydrogen atom or a mercaptoalkyl group selected from a mercaptomethyl group, a 2-mercaptoethyl group, and a 3-mercaptopropyl group; and n is 0, 1, or 2. The invention further provides an epoxy resin composition comprising an epoxy resin and the mercaptoalkylglycoluril, and a method for producing a laminate or a multilayer printed circuit board using the same.
    Type: Grant
    Filed: November 28, 2014
    Date of Patent: July 24, 2018
    Assignee: SHIKOKU CHEMICALS CORPORATION
    Inventors: Takeshi Kumano, Takuma Takeda, Noboru Mizobe
  • Patent number: 10000622
    Abstract: The invention provides a glycoluril represented by the general formula (Z): wherein the group Z represents a carboxyalkyl, a glycidyl or an allyl group; R1 and R2 each independently represents a hydrogen atom, a lower alkyl or a phenyl group; R3, R4 and R5 each independently represents a hydrogen atom or the group identical with the group Z; however, when the group Z is a carboxyalkyl group, R3, R4 and R5 are the same carboxyalkyl groups as the group Z; and when the group Z is an allyl group, R5 represents a hydrogen atom. The invention further provides various resin compositions, for example, polyester resin compositions, epoxy resin compositions, and silicone resin compositions each comprising the glycoluril.
