A colored coating composition containing, as essential components,

Colored films for use in vacuum forming

An improved process for preparing a printed-circuit board, which successively comprises (I) a step of forming a positive photo-sensitive resist film onto a circuit board having a conductive film according to the electrodeposition coating process, (II) a step of irradiating a full dose of an actinic ray onto the positive photo-sensitive resist film through a photomask with which the actinic ray is cut off over a conductive circuit-forming area, (III) a step of developing the resulting resist film, (IV) a step of etching away a deposited copper-clad area, and (V) removing a remaining resist film on the conductive circuit-forming area, the improvement further comprising a step of imparting the resist film in the conductive circuit-forming area an increased alkali resistance prior to development so as to obtain the printed-circuit board having high resolution with good reproductivity without being affected by variations of the developing conditions.

Process for preparing printed-circuit board

Disclosed is a patterned film forming laminated sheet comprising a multi-layer construction prepared by successively laminating a release sheet layer (1), a pressure-sensitive adhesive layer (2), a base sheet layer (3), and a patterned film layer (4) or further laminating a pigmented print layer (5), said patterned film layer (4) being prepared by a process which comprises coating a fluid coating composition containing a powdery magnetic material on one side of the base sheet layer (3) to form a fluid film, and acting a magnetic force on the powdery magnetic material contained in the fluid film in a fluid state to form a pattern.

Patterned film forming laminated sheet

The present invention provides a transfer sheet for marking which comprises a base sheet, a releasant layer, a layer of printed design or like marking (printed layer), a layer of pressure-sensitive adhesive and a release sheet, all superposed in this sequence, the transfer sheet being characterized in that an application film consisting of a film and an adhesive layer is provided over the exposed surface of the printed layer after removing the base sheet and the releasant layer from the transfer sheet.

Transfer sheet for marking

Respectively disclosed is a method of temporarily protecting a surface of a top coating of a coating finished automobile, which method comprieses (A) adhering a plastic film having a releasable pressure-sensitive adhesive layer to a body surface of the coating finished automobile and/or (B) heating a heat-shrinkable plastic film to be shrinked so as to fit to an intended shape and to cover the body surface of the coating finished automobile; which method comprises applying to the body surface of the coating finished automobile a plastic film prepared by intermittently coating a releasable pressure-sensitive adhesive layer to cover the body of the coating finished automobile; which method comprises covering the body surface of the coating finished automobile with a plastic film having a rough surface on a side contacting with a coating surface, and fixing a terminal of the film and heating, when needed, to cover in conformity with a body shape; and which method comprises subjecting a plastic film to vacuum forming to cover a body surface of the coating finished automobile in conformity with the body shape.

Method of protecting coating film

Disclosed is an adhesive sheet for preventing icing, the sheet being characterized in that the sheet comprises a release sheet (1), a pressure-sensitive adhesive layer (2) formed on the sheet (1), a base sheet (3) adhered to the layer (2) and an anti-icing layer (4) formed on the base sheet (3) and that the anti-icing layer (4) is formed from a composition (A) or a composition (B), the composition (A) consisting essentially of:
