elastomers that meet the shearing modulus and wettability
requirements disclosed in Shibano include ethylene-alpha olefin
copolymers having a density of 0.80 to 0.90 g/cm (column 13,3
lines 37-48). There is no express statement in Shibano of any
particular composition distribution of the polymers disclosed
therein.
Kitano relates to tapes using high performance pressure-
sensitive thermosetting adhesives covered with a silicon
release liner. The adhesives of this invention are said to
offer excellent adhesion to metal and painted surfaces,
including oily metal surfaces, as well as high shear and peel
strength and excellent storage properties (column 3, lines 51-
58).
Patterson relates to release sheets used with adhesive
products such as adhesive tapes. The release sheets, having
preferred silicone polymers as release agents, are formed on
paper, nonwoven fabric, polymeric film, or extrusion-coated
paper substrates wherein the coextruded films consist of two
or more layers of polyester films including polybutylene
