摘要： Photosensitive materials are described which may be used in a variety of applications such as making dry transfer materials, resist masks, printing plates and silk screen stencils. The material consists of two carrier sheets may be peeled apart and which are laminated together via at least two interlayers viz. a photosensitive layer and an image forming layer. Prior to exposure, if the carrier sheets are peeled apart the carrier sheet adjacent the photosensitive layer separates wholly from it leaving both photosensitive layer and image forming layer on the other carrier sheet. After exposure, if the sheets which are peeled apart the whole of the photosensitive layer and at least part of the image forming layer remains attached to the carrier sheet adjacent the photosensitive layer.By incorporating adhesive in or adjacent the shearable image forming layer, the photosensitive material may constitute a material from which dry transfers may be manufactured simply by imagewise exposure and peeling apart.

摘要： A method of making signs is disclosed in which a photographically sensitive material is imagewise exposed and developed. The developed image is so constituted that, under the action of heat and pressure, it may be made to adhere to a surface of a transparent or translucent sheet, e.g. of plastics or glass, to form a sign in which the legend is visible through and protected by the sheet. In order to render the legend more visible, a coating or layer may be applied over the legend which accordingly forms a background to the legend as viewed through the sheet.Production of the legend photographically gives very great flexibility in terms of letter size, spacing and the like and allows the production of "one off" signs on a rapid and economic basis. A simple hot press may be used to adhere the legend to the sign sheet.
摘要翻译：公开了一种制作符号的方法，其中对照相敏感材料进行成像曝光和显影。显影图像的构造使得在热和压力的作用下，可以使其粘附到透明或半透明片材的表面，例如，的塑料或玻璃，以形成一个标志，其中图例可以通过片材可见和保护。为了使图例更可见，可以在图例上施加涂层或层，从而相应地通过片材观察到形成图例的背景。传说的生产在信件尺寸，间距等方面具有非常大的灵活性，并且允许在快速和经济的基础上产生“一次”标志。可以使用简单的热压机将图例粘贴到标牌上。
