A flexible optical solar reflector (FOSR) which may be also used as an outermost layer of a multilayer thermal insulator comprising:
a heat radiation layer (2) of a resin selected from the group consisting of poly [(4'-phenoxy-4-carbonyl)diphenyl ether] represented by the following general formula of:
and poly (ether imide) represented by the following general
wherein R is a meta-substituted phenyl group, a para-substituted phenyl group or a 4,4'-substituted phenyl ether group; and
a solar light reflecting layer (1) disposed on said heat radiation layer (2) and made of a thin coating of a metal selected from the group consisting of silver and aluminium, A CeO2 covering layer may be disposed over the heat radiation layer. The FOSR is excellent in resistance to ultraviolet rays, particularly in resistance to electron beam, and superior in optical and mechanical properties.
