CLASS: IC: B32B027-32. APPLICATION: JP 71-36918 31 May 1971. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Polypropylene [9003-07-0] and polyester films were laminated with itaconic acid-Me acrylate-vinylidene chloride copolymer (I) [25249-60-9] (residual peroxide content <0.001%), using acrylic polymers contg. 0.5-20% Ti compd. to give composite films with good interlayer adhesion, water rsistance, heat sealability, and gas impermeability. For example, a 22 m-thick bias-stretched polypropylene film (corona discharge-treated to contact angle 65°) was coated to 1 g(solids)/m2 with a 30% solids aq. compn. contg. 1.2::1.8 (mol ratio) acrylic acid-Et acrylate-Me methacrylate-N-methylolacrylamide copolymer [30643-08-4] and Ti(SO4)2 in ratio, dried at 140° (wind velocity 40 m/s) for 6 s, topped to 5 g(solids)/m2 with a 50% solids aq. compn. contg. 1:8:91 I and Na2SO3 (for reduced peroxide content) in .5 ratio, and dried at 120° (wind velocity 40 m/s) for 5 s to give a composite film with peel strength 250 g/cm2 and 190 g/cm2 (after 30 min in boiling water), while delamination was obsd. in the boiling water test with a composite using the adhesive not contg. Ti(SO4)2.

Biaxially oriented polyester films with backside surface roughness appropriate for servo track formation, and magnetic tapes using them

Biaxially oriented polyester films with backside surface roughness appropriate for servo track formation, and magnetic tapes using them.Several substances are used for example 25230-87-9 and 30643-08-4 which are their cas registry numbers.

CLASS: ICM: C08J005-18. ICS: C08L067-00; C08L101-00; G11B005-73. APPLICATION: JP 2003-194825 10 Jul 2003. DOCUMENT TYPE: Patent CA Section: 77 (Magnetic Phenomena) Section cross-reference(s): 38 The invention relates to polyester films with center-line-av. surface roughness (Ra) on one side 3-30 nm, that on the other side 0.5-10 nm, and gloss on at least one side 20-170%. The films may have 31 polymer layers (e.g., acrylic polymers, polyurethanes, fluoropolymers) with refractive index 1.20-1.60. .
