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:
An adhesion-including film is provided, wherein the total light transmittance is varied in a width direction of the film. The adhesion-including film includes a mold release film, a first adhesive layer disposed on this mold release film, a second adhesive layer disposed on the first adhesive layer, a base film on the second adhesive layer, and an antireflection film disposed on the film surface opposite to the second adhesive layer of the base film. The first adhesive layer is highly colored as compared with the second adhesive layer. The second adhesive layer may be colorless. The thickness of the central portion of the first adhesive layer in the width direction of the film is larger than the thicknesses of both end sides. The total thickness of the first adhesive layer and the second adhesive layer is uniform all over the film.
