Claim 3

A flexible reflex-reflecting transfer film which when laminated to a fabric provides a product having a high degree of color intensity and resistance to degradation by dry cleaning, said structure comprising a monolayer of glass beads within the size range of 25 to 250 microns and having a refractive index of at least 1.8, said beads being firmly approximately hemispherically embedded and bonded in a flexible binder layer comprising a substantially transparent, clear and colorless flexible resin and specularly reflective nacreous pigment particle platelets having a maximum dimension which falls within the range of eight to 30 microns and which is less than the diameter of said beads, individual beads having platelets arranged in cup-like fashion about the embedded portion of said beads, the concentration of said platelets being at least 15 percent by weight of the total solids in said binder.

Claim 4

A reflex-reflecting transfer film according to claim 4 in which the glass beads are in the size range of 50 to 90 microns and have a refractive index of at least 1.9, and the nacreous pigment particles have an average maximum dimension within the range of 16 to 24 microns.

Claim 5

A reflex-reflecting transfer film according to claim 5 in which the transparent binder comprises a mixture of about equal amounts of a highly crystalline polyurethane resin and a vinyl resin which is a copolymer containing a major proportion of polyvinyl chloride and a minor proportion of polyvinyl acetate.

Claim 6

A transfer film according to claim 4 in which the binder layer has thereover, on the side opposite the protruding glass beads, a thermoplastic opaque colored layer.

Claim 7

A transfer film according to claim 1 laminated to a fabric.

Claim 8

A transfer film according to claim 7 in which a thermoplastic adhesive layer is superimposed on said colored layer, the adhesive layer is protected by a low adhesive release liner and the portion of the glass beads protruding from the reflective layer are embedded in a dry strippable carrier.

Claim 9

A reflex-reflecting structure which is resistant to degradation by laundering and dry cleaning and which has a high degree of color intensity, said structure comprising a layer of fabric and a surface layer thereon comprising a substantially clear and colorless transparent flexible resin into which are firmly and approximately hemispherically embedded and bonded glass beads within the size range of 25 to 250 microns and having a refractive index of at least 1.8, and containing specularly reflective nacreous pigment particle platelets having a maximum dimension which falls within the range of eight to 30 microns and which is less than the diameter of said beads, at least some of said platelets being disposed in at least approximately tangential and cup-like relationship to the embedded surfaces of said beads, the concentration of said platelets being at least 15 percent by weight of the total solids in said resin.

Claim 10

A reflex-reflecting structure according to claim 10 having a flexible opaque color layer between said adhesive layer and said binder layer.

Claim 11

The reflex-reflecting structure of claim 10 wherein said nacreous pigment particle platelets are essentially the sole particulate material in said binder layer.

Claim 12

A reflex-reflecting transfer film according to claim 4 in which said binder layer also includes up to about 50 percent by weight based on solid resin binder, of a colorant.

Claim 13

A reflex-reflecting transfer film according to claim 6 in which the binder includes about one part of epoxy resin for each 40 parts of urethane and vinyl resin.

Claim 14

A reflex-reflective structure according to claim 10 in which said binder layer comprises the reaction produce of a mixture of about equal parts by weight of a highly crystalline polyurethane resin, and a vinyl resin, said vinyl resin being a copolymer of a major proportion of polyvinyl chloride and a minor proportion of polyvinyl acetate, and of about 1 part by weight of an epoxy resin for each 40 parts of said urethane and vinyl resins.

Claim 15

A reflex-reflective structure according to claim 10 in which said binder layer also includes up to about 50 percent by weight based on solid resin binder, of a colorant.
