Laminating materials for low pressure laminates,method of making same,and laminates thereof
Abstract
Abstract THIS INVENTION RELATES TO IMPROVED LAMINATING MATERIALS, ESPECIALLY SATURATING PAPER, CONTAINING DIACETONE ACRYLAMIDE, OR AN ANALOGUE OR METHYLOLATED DERIVATIVE THEREOF (DAA), WHICH ARE ESPECIALLY USEFUL IN THE PRODUCTION OF LOW-PRESSURE LAMINATED STRUCTURES AS EXEMPLIFIED BY LOWPRESSURE POLYESTER LAMINATES. THE IMPROVED LAMINATING MATERIALS, E.G., SATURATING PAPER, ARE CHARACTERIZED BY A HIGH DEGREE OF WATER-RESISTANCE IMPARTED TO LOW-PRESSURE LAMINATES EMBODYING THE SAME, AS WELL AS BY EASE AND UNIFORMITY OF SATURATION WITH THE LAMINATING RESIN AND BY UNIFORMITY OF COLOR OF THE ULTIMATE LAMINATE AS WELL AS THE LAMINATING MATERIAL, E.G., THE SATURATING PAPER ITSELF. THE DISCLOSURE ALSO RELATES TO CORRESPONDING RESIN-SATURATED LAMINATING MATERIALS ("PREPREGS"), A METHOD OF MAKING SUCH IMPROVED LAMINATING MATERIALS, AND LAMINATES THEREOF HAVING SUCH SUPERIOR WATER-RESISTANCE.
