Abstract: MANY OF THE PHYSICAL PROBLEMS ENCOUNTERED IN THE PRUDUCTION OF AN OPTICALLY PERFECT LAMINATION BETWEEN POLYMETHYL METHACRYLATE AND CELLULOSE ACETATE BUTYRATE MAY BE OBVIATED BY UTILIZING AN ADHESIVE COMPRISING APPROXIMATELY 95% METHYL METHACRYLATE MONOMER, APPROXIMATELY 4% NITROCELLULOSE HAVING A VISCOSITY WITHIN THE RANGE OF 600 TO 1000 SECONDS-1 AND ABOUT 1% OF AN INITIATOR FOR THE MONOMER.

Abstract: Laminar structures such as identification (ID) cards and the like including an information-bearing surface, e.g., a photograph, having affixed thereto a substantially transparent overlay including a layer at least a portion of which is lightpolarizing and which is preferably dyed or stained to provide a protective security feature for said structure, the laminar structure being characterized as having a strong dry bond, but possessing a poor wet bond whereby attempts to separate the information-bearing surface from the overlay with the aid of a solvent, e.g., water, will cause the polarizing layer to curl up and be effectively destroyed so that it cannot be reused.

Abstract translation: 诸如识别（ID）卡等的层状结构包括信息承载表面，例如照片，其具有固定到其上的基本上透明的覆盖层，其包括至少一部分是光偏振的并且优选地被染色的层， 染色以提供所述结构的保护安全特征，层状结构的特征在于具有强的干结合，但是具有差的湿粘结，从而借助于溶剂将信息承载表面与覆盖物分开，例如， 水会导致偏振层卷起并被有效地破坏，从而不能重复使用。

Abstract: Novel improved dye layers especially suitable for use in plastic laminations, such as those involved in plastic optical products. The layer comprises a dye substantially uniformly dispersed in a cellulose derivative matrix wherein one surface of the matrix has been converted to cellulose.
