A method of forming a spacer for supporting two substrates which constitute a liquid crystal panel, wherein the spacer is disposed between the two substrates, at least one of which has thereon an alignment layer which has been subjected to aligning treatment, comprising the steps of: (1) laminating the substrate having the alignment layer on a transfer sheet comprising projections of substantially uniform thickness on a temporary support in such a manner that the projections closely contact the alignment layer, and (2) peeling-off the temporary support to transfer the projections onto the alignment layer. The inventive method forms a spacer through a simple step and at a uniform density, and prevents damage of an aligning layer.

An image formation process uses two light-sensitive elements comprising first and second adhesive light-sensitive layers which become nonadhesive upon exposure to light, respectively, and first and second toner elements comprising toner layers (a') and (b') of hues (a) and (b), respectively. The process steps include:A) imagewise exposing the first light-sensitive layer;B) contacting the first light-sensitive layer with layer (a') in the first toner element;C) separating the first toner element and the first light-sensitive element, transferring the toner layer portion corresponding to the unexposed portion of the light-sensitive layer to the light-sensitive layer and leaving the toner layer portion corresponding to the exposed portion of the light-sensitive layer on the support for the first toner element;D) contacting the adhesive surface of an image receiving element with the surface of the toner layer of the first toner element on which the toner layer has been left corresponding to the exposed portion of the first light-sensitive layer;E) separating the image receiving element and the first toner element, transferring the toner layer to the image receiving element;F) repeating A) to C) with the second light-sensitive element and toner element, respectively; andG) contacting the surface of the transferred toner layer of the image receiving element on which the hue (a) toner layer has been transferred with the surface of the hue (b) toner layer and separating the image receiving element and the second toner element, transferring the hue (b) toner layer to the image receiving element.
摘要:
A photosensitive transfer material comprises a temporary substrate having provided thereon an alkali-soluble thermoplastic resin layer, an intermediate layer, and a photosensitive resin layer in this order, the interlaminar adhesion in the transfer material being the smallest at the interface between the thermoplastic resin layer and the temporary substrate. The photosensitive resin layer can be transferred to a permanent substrate without involving failure due to fine dust, air bubbles or unevenness of the permanent substrate. An image can be formed with the transfer material by adhering the transfer material to a permanent substrate at least under heat and, after stripping the temporary substrate, imagewise exposing the photosensitive resin layer to light, and processing the transferred layers to develop the photosensitive resin layer. If the thermoplastic resin layer and the intermediate layer are first removed with a processing method with which the photosensitive resin layer is not substantially developed and then the photosensitive resin layer is developed using a processing solution other than used for revmoving the thermoplastic resin layer and the intermediate layer, excessive fatigue of the developing solution for the photosensitive resin layer and unevenness of development can be prevented.
