Abstract: The method of producing a laminate for receiving a chemical plating comprises the step of forming a thermosetting adhesive layer containing a butadiene-based rubber on at least one surface of a peel-resistant insulating sheet. After the adhesive layer has been cured substantially completely, the adhesive-bearing sheet is bonded to a base material so as to obtain an integral laminate, followed by coarsening the outermost surface of the laminate on the side of the insulating sheet. A laminate with a metalized surface is obtained, if a chemical plating is applied to the coarsened surface of the laminate.

Abstract: In a grid structure for a color picture tube of the type comprised of a pair of elongated frame elements disposed in substantially parallel, spaced apart relation at the top and bottom, respectively, of the grid structure, a pair of mechanically resilient brace members having mid-portions extending between the frame elements at the opposite sides of the grid structure and end portions affixed to the frame elements for maintaining the latter in their spaced apart relation, and a plurality of grid wires defining slits therebetween extending between the frame elements and being welded or otherwise affixed to the latter adjacent the opposite ends of the grid wires while the grid wires are longitudinally tensioned and the brace members are prestressed by forces acting on the frame elements in the directions to urge the frame elements toward each other; each brace member has a cross-sectional shape, such as, a rectangular shape, providing different section moduli in respect to correspondingly different axes passing
