Disclosed is a waterproofing membrane that comprises a carrier sheet, a pressure sensitive adhesive layer on one surface of the carrier sheet, and a protective coating layer on the adhesive layer. The protective coating layer comprises a highly reflective protective coating layer operative to bond to concrete cast against it, particularly one that is produced from an aqueous coating comprising an acrylic emulsion, a filler, and a white pigment. The pigment volume concentration of the filler plus white pigment is greater than or equal to 55% by volume. The protective coating layer protects the membrane against weather exposure, tolerates foot traffic and strongly adheres to concrete cast against it. Also disclosed is a waterproofing membrane comprising a carrier sheet, a pressure sensitive adhesive layer, a protective coating layer, and a highly releasable bonding layer. The preferred highly releasable bonding layer comprises nanoscale silica and a binder.

A protective tape used for optical member includes a plastic film base, an adhesive layer formed on one side of the plastic film base, and a treated layer formed on an opposite side of the plastic film base. The treated layer is formed with a treat agent containing a silicone resin and a cellulose polymer. The protective tape used for optical member is enabled to direct print with an ink on the treated layer and have a low adhesive property with the adhesive applied to an optical film.

368,199. Adhesive tape. KODAK, Ltd., Kodak House, Kingsway, London.- (Assignees of Dow, E. M. ; Kodak Park, Rochester, New York, U.S.A.) Aug. 26, 1931, No. 24003. Convention date, Aug. 29, 1930. [Class 140.] Adhesive tape comprises a cloth, paper or like support coated on one side with an adhesive, and on the other side with a composition containing an acyl ester of cellulose having less than six carbon atoms in the acyl group, preferably cellulose acetate. Any type of adhesive may be used, for example, that commonly used in the production of medical adhesive tape. The cellulose ester composition may contain cellulose acetate, a plasticizer, for example diethyl phthalate, triphenyl or tricresyl phosphate, or monochlor-naphthalene, and a solvent such as acetone and ethyl lactate, or acetone, a high boiling solvent, and a diluent. In place of cellulose acetate, cellulose propionate or cellulose butyrate may be used. Smooth paper, cloth or other fabric, or corrugated, crinkled or otherwise deformed paper or cloth may be used as the support. Specification 348,694 is referred to.
摘要:
The present invention relates to a predominantly biodegradable double-separating film and comprising at least one carrier layer (a) that is based on at least one biodegradable polymer, and at least one release layer (b) that is based on at least one cured polysiloxane. The curing of said release layer is based, at least partially, on at least one cross-linked monomer or oligomer additive. Said additive also promotes adhesion between the carrier layer (a) and the release layer (b), and has no siloxane groups but does have at least two functional groups, of which at least one is a functional group with at least one carbon double bond. No adhesion-promoting layer is present between the carrier layer (a) and the release layer (b). In addition the invention relates to the use of such a separating film as a removable protection and cover film.

摘要:
Pressure-sensitive adhesive tape having a backsize which is a blend of (1) 5-80 parts cellulose acetate butyrate and (2) 95-20 parts copolyester and/or acrylate copolymer has both printability and low-unwind characteristics. After the back is printed, the tape can be wound into a roll and unwound without destroying the legibility of the printing. The backsize is especially useful on tapes having a polyester or unplasticized polyvinyl chloride film backing, as well as on filament tape or other tapes which have aggressive pressure-sensitive adhesives.
