Abstract:
PROBLEM TO BE SOLVED: To generate microgases with high gas generation power from microareas and to intermittently shut off or change the direction of the liquid flow continuously discharged from a nozzle with high accuracy. SOLUTION: The gas generating composition is composed of a gas generating agent and a light absorbent and can generate the gases in the microareas by microheating sources. The gas generating member can be obtained by forming a tight contact layer 2 and a gas generating layer 3 containing the gas generating agent (nitrocellulose, etc.), and the light absorbent (carbon black, etc.), and having >=20 μm thickness on the surface of a supporting body 1. The tight contact layer 2 firmly sticks the supporting body 1 and the gas generating layer 3. A coating layer 4 may be formed on the surface of the gas generating layer 3 in order to hold gaseous pressure.

Abstract:
PURPOSE:To obtain a pressplate material having a high strength of a thermally decomposable photosensitive layer, a high adhesion to a PET film as a substrate, and a superior durability by a method wherein an adhesive layer is provided between the photosensitive layer containing a nitrocellulose, a carbon black, and a binding resin and the substrate. CONSTITUTION:In a pressplate, esp. a laser engraving pressplate, an adhesive layer is provided between a photosensitive layer containing a nitrocellulose, a carbon black, and a binding resin and a substrate. The photosensitive layer is composed of a nitrocellulose, a carbon black, and a binding resin and bonded to a PET film (biaxially oriented polyester film) as the substrate through the adhesive layer. As the binding resin, a binding resin superior in resistance to solvents and resistance to wear, esp. an aromatic polyester, is used. For the adhesive layer, a material ideally bonded to both the substrate and the photosensitive layer and never affected by an organic solvent and water is used. For example, a polyurethane resin is used.
