    摘要: There is disclosed a process for producing pyrogallol by dehydrogenation of cyclohexane-1,2,3-triol in the presence of a platinum group metal catalyst in an inert gas stream. The catalyst contains, as modifier, (a) at least one alkali metal salt and/or (b) at least one member selected from the group consisting of gold, tellurium, silver, arsenic, selenium, indium, antimony, bismuth, copper and zinc, with the Pd-Te catalyst being preferred. The catalyst ingredients are supported on a carrier. The process gives high selectivity of pyrogallol.

    摘要: The present invention provides a photo-curable transfer sheet by which an optical information recording medium having small thickness and high capacity can be advantageously prepared, the photo-curable transfer layer of the sheet cured in the production of the optical information recording medium having excellent adhesion to the reflective layer such silver alloy and easy peeling property from the stamper to easily bring about the transfer layer having an uneven surface such as pits, etc accurately formed along an uneven surface of the stamper. The photo-curable transfer sheet has a photo-curable transfer layer comprising a photo-curable composition deformable by application of pressure, wherein the photo-curable composition comprises a polymer and a reactive diluent having a photopolymerizable functional group, and the reactive diluent has at least one hydroxyl group and an acryloyl group and/or methacryloyl group, the total of acryloyl group and/or methacryloyl group being at least two. The invention also provides a process for the preparation of an optical information recording medium using the sheet, and the optical information recording medium.
