The present invention provides a method of controlling the distribution of a fluid on a body that features compensating for varying distribution of constituent components of a composition that moved over a surface of a substrate. To that end, the method includes generating a sequence of patterns of liquid upon a substrate, each of which includes a plurality of spaced-apart liquid regions, with voids being defined between adjacent liquid regions. A second of the patterns of liquid of the sequence is arranged so that the liquid regions associated therewith are in superimposition with the voids of a first of the patterns of liquid of the sequence.

A nonaqueous pressure-sensitive adhesive for a medicinal tape preparation for percutaneous absorption comprising (a) a support, (b) a pressure-sensitive adhesive layer containing a drug and a nonaqueous pressure-sensitive adhesive and (c) a release film laminated in that order, and a medicinal tape preparation for percutaneous absorption comprising the adhesive. The nonaqueous pressure-sensitive adhesive may comprise a copolymer obtained by copolymerization of a (meth)acrylic monomer having an acetoacetyl group in the molecule and one or more monomers from among other (meth)acrylic monomers without acetoacetyl groups and copolymerizable vinyl monomers, in a nonaqueous solvent. Suitable (meth)acrylic monomers having an acetoacetyl group in the molecule are acetoacetoxyalkyl methacrylates, and especially 2-acetoacetoxyethyl methacrylate. The copolymer nonaqueous pressure-sensitive adhesive of the invention, comprising a (meth)acrylic monomer having an acetoacetyl group as a constituent monomer, is capable of containing large amounts of lipophilic oily substances in the pressure-sensitive adhesive layer, and during heat drying, the acetoacetyl groups undergo self-crosslinking to form a network structure as the solvent evaporates off, so that large amounts of oily substances such as the plasticizer can be included in the network structure. The pressure-sensitive adhesive of the invention uses no polyamine derivatives, isocyanate compounds, polyvalent metal chelate compounds, etc., as crosslinking agents, and therefore toxicity is not a concern and skin is not irritated. A medicinal tape preparation for percutaneous absorption of the invention has superior adhesive strength and cohesive strength, and is highly safe with low skin irritation. It also has excellent drug release and percutaneous absorption properties.

A patch containing a support and an adhesive layer formed on at least one surface of the support, wherein the adhesive layer contains an elastomer obtained by crosslinking a polymer having a butadiene skeleton in the presence of organic peroxide, wherein the patch has good adhesion property and maintain this quality for a long time.

An adhesion method capable of strongly adhering two members without using an adhesive and without impairing a fine structure or optical properties of a joining surface, and a biochemical chip and optical component made by the same are provided.The adhesion method includes step A of forming a coating film 13 of a first film compound having a first photoreactive functional group on a first joining surface 11 of a first member 21, step B of forming a coating film 14 of a second film compound having a second photoreactive functional group on a second joining surface 12 of a second member 22, and step C of bringing the first joining surface 11 into contact by pressure with the second joining surface 12 while setting a coupling agent having at least one coupling reactive group that forms a covalent bond with the first photoreactive functional group and the second photoreactive functional group by light irradiation to be in contact with the first and second photoreactive functional groups, and conducting light irradiation to form covalent bonds.

The invention discloses a preparation method of a hydrocracking catalyst. The catalyst is first to make the mixed solution A containing Ni and Al and the alkaline solution of sodium tungstate co-flow for colloidal reaction, then aging the obtained slurry, and mix the mixed solution B containing Si and Al components with the alkaline solution of sodium tungstate The solution is added in parallel to the above-mentioned aged slurry to carry out gelation reaction, and then the suspension of molecular sieves is added to carry out aging, and then dried and shaped to make a hydrocracking catalyst. The hydrocracking catalyst is suitable for medium oil type hydrocracking catalyst and has good activity and selectivity.
