<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a laminate by curing a curable resin composition held and sealed between a pair of basal plates, where, at releasing reduced-pressure atmosphere, the diameter of voids remaining in the curable resin composition layer in the sealed space can be made smaller, and thereby the time required until the voids remaining in the curable resin composition layer disappear can be shortened. <P>SOLUTION: In the method, formation of a laminate precursor of the curable resin composition held between a pair of basal plates is conducted in a reduced-pressure atmosphere satisfying conditions that the atmospheric pressure P is 0.1-1,000 Pa and the pressure gradientΔP/ΔT (Pa/sec) under the atmospheric pressure is -1 (Pa/sec)≤ΔP/ΔT≤0 (Pa/sec); and the amountΔP (Pa) of pressure variation, from the formation of the laminate precursor until immediately before when the laminate precursor is put in a second pressure atmosphere higher in atmospheric pressure than that of the reduced-pressure atmosphere, is held at: -1 (Pa)≤ΔP≤2 (Pa). Further, the laminate precursor is pressurized when it is put in the second pressure atmosphere. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
