Abstract
Abstract A noiseless, printable self-adhesive tape comprises a substrate in the form of an olefinic polymer film, a pressure-sensitive adhesive layer on one face of the substrate, and a printable, non-stick layer on the other face of the substrate. The non-stick layer is formed by a composition including a chlorinated olefinic resin and an acrylic resin in which the ratio by weight of the acrylic resin to the chlorinated olefinic resin may vary from 4:1 to 1:4. The composition also includes from 0.1 to 2 parts by weight of a non-stick agent per 100 parts by weight of the sum of the first two components, the non-stick agent being prepared by the reaction of an alkyl isocyanate with polyvinyl alcohol and a reactive silicon compound.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A pressure-sensitive self-adhesive tape including: a substrate in the form of an olefinic polymer film, a pressure-sensitive adhesive layer on one face of the substrate, and a printable, non-stick layer on the other face of the substrate, wherein the non-stick layer is composed of a composition including a chlorinated olefinic resin and an acrylic resin in which the ratio by weight of the acrylic resin to the chlorinated olefinic resin is from 4:1 to 1:4, the composition also including from 0.1 to 2 parts by weight of a non-stick agent per 100 parts by weight of the sum of chlorinated olefinic resin and the acrylic resin, the non-stick agent being prepared by the reaction of an alkyl isocyanate with polyvinyl alcohol and a silicone/glycol polymer.
Claim 2
Dependent Claim
125 words
A pressure-sensitive self-adhesive tape including: a substrate in the form of an olefinic polymer film, a pressure-sensitive adhesive layer on one face of the substrate, and a printable, non-stick layer on the other face of the substrate, wherein the non-stick layer is composed of a composition including a chlorinated olefinic resin and an acrylic resin in which the ratio by weight of the acrylic resin to the chlorinated olefinic resin is from 4:1 to 1:4, the composition also including from 0.1 to 2 parts by weight of a non-stick agent per 100 parts by weight of the sum of chlorinated olefinic resin and the acrylic resin, the non-stick agent being prepared by the reaction of an alkyl isocyanate with polyvinyl alcohol and a silicone/glycol polymer.
Claim 3
Dependent Claim
18 words
A self-adhesive tape according to claim 1, wherein the olefinic polymer used for the substrate film is polypropylene.
Claim 4
Dependent Claim
23 words
A self-adhesive tape according to claim 1, wherein the chlorinated olefinic resin has a chlorine content of between 24 and 35% by weight.
Claim 5
Dependent Claim
25 words
A self-adhesive tape according to claim 1, wherein the acrylic resin is selected from the group consisting of methyl methacrylate, methyl acrylate, and isobutyl methacrylate
Claim 6
Dependent Claim
43 words
A self-adhesive tape according to claim 1, wherein the non-stick agent is formed with a polyvinyl alcohol having a Brookfield viscosity of between 5 and 45 mPa.s and a silicon/glycol surface-active copolymer as the silicon compound and stearyl isocyanate as the alkyl isocyanate.
Claim 7
Dependent Claim
96 words
A self-adhesive tape according to claim 1, wherein the non-stick layer is formed by a composition including a chlorinated olefinic resin and an acrylic resin in which the ratio by weight of the acrylic resin to the chlorinated olefinic resin is from 1:1 to 1:2, the composition also including from 0.3 to 0.7 parts by weight of a non-stick agent per 100 parts by weight of the sum of the chlorinated olefinic resin and the acrylic resin, the non-stick agent being prepared by the reaction of an alkyl isocyanate with polyvinyl alcohol and a silicone/glycol polymer.
