Abstract

PURPOSE: To enhance the productivity of the title tape or sheet and the light scattering effect thereof by uniformly applying adhesive fine particles to at least one side of a light transmissive substrate at a state where the particles are bonded to each other and unified.
CONSTITUTION: 5W150g/m2 of acrylic adhesive fine particles 2 with a middle diameter of 5W100μ are applied about uniformly to one side or both sides of light transmissive substrate 1 such as polyester film at a state where the particles are bonded to each other and unified without isolation separation or they are bonded and unified with other adhesive or non-adhesive layer in-between, forming a rough surface of corrugated structure. When the particles are isolation-separated from each other, a flat portion tends to form between the particles, and this portion does not scatter light to pass it straight. Thus, a light scattering tape or sheet with high light scattering effect is obtained with high productivity.
