  • Patent number: 10632777
    Abstract: When water pressure transfer of decorative layer or layers is carried out on an article using a water pressure transfer sheet 202 having a non-extensible decorative layer 22 providing hologram function and an extensible decorative layer 24 of print pattern sequentially from a top of said water pressure transfer sheet, a plurality of preformed cracks 26 are formed in said non-extensible decorative layer 22 of said water pressure transfer sheet 201 before said water pressure transfer sheet 202 lands on water, then an activating agent for wetting and activating said extensible decorative layer 24 is applied, and thereafter said water pressure transfer sheet lands on the water whereby water pressure transfer is carried out having high profile followability.

  • Patent number: 8927237
    Abstract: An acylating agent and a hydrolase are caused to act on a hydroxypyranone represented by formula (I) in a water-containing organic solvent, to thereby produce an acyloxypyranone compound represented by formula (II) (wherein R1 represents an acyl group). Then, an acetylene organic metal compound represented by formula (III) (wherein R2 represents a hydrogen atom or a tri-substituted silyl group, and M represents an alkali metal atom, aluminum, or a magnesium monohalide) and a coordinating additive are caused to act on the acyloxypyranone compound represented by formula (II), to thereby produce an alkyne compound represented by formula (IV). The alkyne compound represented by formula (IV) is hydrolyzed with acid, to thereby produce a dihydrofuran compound represented by formula (V).

  • Patent number: 5318874
    Abstract: A composition for forming a photosensitive coating is disclosed which includes:(a) a photosensitive agent which is an o-naphthoquinone diazide compound,(b) a polyvinylpyrrolidone compound, and(c) a stannic halide, wherein the o-naphthoquinone diazide compound is present in an amount of 5-50 parts by weight per 100 parts by weight of the polyvinylpyrrolidone compound and the stannic halide is present in an amount of 4-40% based on the weight of the o-naphthoquinone diazide compound.

  • Patent number: 5231202
    Abstract: A phosphine compound represented by formula (I): ##STR1## wherein Ph represents a phenyl group; and R represents a lower alkyl group or --OR.sup.1, wherein R.sup.1 represents a hydrogen atom, a cycloalkyl group having from 5 to 7 carbon atoms, or an alkyl group having from 1 to 6 carbon atoms which may be substituted with a halogen atom, a lower alkoxy group, a lower alkoxy group-substituted lower alkoxy group, or a phenyl group, and a transition metal complex using the phosphine compound (I) as a ligand are disclosed. The transition metal complex, when used as a catalyst for various enantioselective synthesis reactions, e.g., enantioselective silylation reaction, provides a desired product in high yield at high optical purity. The absolute configuration of the product can be arbitrarily selected by selecting the optical isomer of the ligand in the transition metal complex catalyst.
