  • Patent number: 11608447
    Abstract: Disclosed are a cell culture substrate that can be modified from its cell-inadhesibleness to make it cell-adhesible, by a convenient and low-cost treatment, and particularly, a substrate that allows position-specific culture of one or more kinds of cells. The substrate has on its surface a layer made of a photomodifiable polymer that comprises a monomer, as component (A), represented by Formula (1): wherein R1 denotes hydrogen or a methyl group, and R2 denotes an alkyl group having 1-22 carbon atoms, respectively, and n denotes an integer of 1-30, and a component (B) having a trialkoxysilyl group, which forms a layer.
    Type: Grant

  • Publication number: 20180305573
    Abstract: Provided are a clear coating composition which is used for top coats, the composition containing a crosslinking agent and a functional group-containing (meth)acrylate polymer formed by polymerization of a monomer component that includes an aromatic ring-containing (meth)acrylate and a functional group-containing monomer. Also provided is a clear coat composition which is used for top coats, the composition containing a crosslinking agent and a functional group-containing (meth)acrylate polymer formed by polymerization of a monomer component that includes a functional group-containing monomer and a fluorine atom-containing monomer. This clear coat composition has low colorability, has a high refractive index without the use of a filler, provides excellent glossy even when a filler is used, and can be applied to a thick film.

  • Patent number: 7171282
    Abstract: The present invention provides a shell plating developing method leading to reduction of the amount of machining and improvement of the efficiency in manufacturing the shell plating. In the shell plating developing method according to the invention, a shell plating lattice system is constituted, and the directions in which the curvature of a shell plating P at each lattice point of the shell plating lattice system is maximum and minimum are determined (s102). Also, lines extending in the directions in which the absolute value of the curvature is large and small are determined as a first connection line L1 and a second connection line L2 (s104). The first connection line L1 is developed as a straight line on a flat plate P? while the length of the first connection line L1 is maintained.
