A laser-markable, acrylic resin-based laminate having a thickness of 100 to 200 &#x3bc;m and including (A3) a pigmented layer made of a crosslinked acrylic resin obtained by crosslinking an acrylic resin composition having a hydroxyl value of 10 to 100 mg KOH/g, (B3) a base layer made of a crosslinked acrylic resin obtained by crosslinking an acrylic resin composition having a hydroxyl value of 18 to 40 mg KOH/g, and (C3) a destructible layer made of a crosslinked acrylic resin obtained by crosslinking a mixture of an acrylic resin composition having a hydroxyl value of 20 to 35 mg KOH/g and polymer beads.

Heat-resistant brittle label

Retroreflective sheeting including a retroreflective base having a light-incident layer on its light-incident side and a fluorine-containing resin film having a total light transmittance of 80% or more which is provided on the light-incident layer by an adhesive layer, a printed layer made of discontinuous printed parts is provided between the film and the adhesive layer. The printed layer does not cause the film to separate.

Retroreflective sheeting having printed layer

Retroreflective sheeting ( ) comprises a reflective base ( ), a transparent film layer ( ) which is colored different from the color of reflected light of the reflective base ( ) and a pressure-sensitive adhesive layer ( ). The transparent film layer ( ) is removably provided on the reflective base ( ) via the pressure-sensitive adhesive layer ( ). Part ( &prime;) of the transparent film layer ( ) is to be cut out on use so that the transparent film layer ( ) may form a desired image. The peel strength between the transparent film layer ( ) and the reflective base ( ) is 25 to 400 gf/25 mm. After the transparent film layer ( ) is pressed to the reflective base ( ) under a pressure of 5 kgf/cm , the peel strength between the transparent film layer ( ) and the reflective base ( ) is 700 gf/25 mm or greater.

Retroreflective sheeting

Lens type functional retroreflective sheeting and method of producing

The present invention discloses lens-type retroreflective sheeting excellent in appearance and having constant thickness and desired retroreflective performance, wherein the transparent microspheres in the retroreflective layer are composed of transparent microspherical lenses (A) having a refractive index of 1.8 or more and transparent microspherical fillers (B) having a refractive index different by at least 5% from the refractive index of the lenses (A).

Lens-type retroreflective sheeting

The present invention provides a method for producing retroreflective sheeting useful for marking or the like of signs such as road signs and construction signs; number plates of vehicles such as motorcars and motorcycles; materials for safety such as clothes and life jackets; signboards, etc., and the method is a method for producing retroreflective sheeting, which comprises embedding glass beads substantially in a monolayer in a temporary support at least one surface of which is composed of a thermoplastic resin in such a manner that at least part of each bead is embedded in the thermoplastic resin; forming a vapor-deposited metal film on the surface in which the glass beads were embedded; superposing thereon a thermoformable support film; pressing the resultant superposed matter under heating to embed the vapor-deposited metal film portion of each of the glass beads in the support film; and peeling the temporary support from the superposed matter in such a manner that the glass beads remain in the support film, said method being characterized in that a thin film containing a coupling agent is previously formed on the vapor-deposited metal film of the temporary support in which the glass beads are embedded and on which the vapor-deposited metal film is then formed, and then the support film is superposed thereon.

Ultraviolet luminescent retroreflective sheeting

The present invention comprises lens-type retroreflective sheeting which is excellent in appearance and having constant thickness and desired retroreflective performance, wherein the transparent microspheres in the retroreflective layer are composed of transparent microspherical lenses (A) having a refractive index of 1.8 or more and transparent microspherical fillers (B) having a refractive index different by at least 5% from the refractive index of the lenses (A).

This invention provides a capsule type retroreflective sheeting excelling in strength and longterm weatherability, the connecting walls, which partially connect the light-transmitting protective film and support film while retaining the spaces between the two films, being free of internal flaws such as deficiently filled portions and having uniform structure and shape. The capsule type retroreflective sheeting in which the connecting walls are formed by partially thermofusing and thermoforming the support film is characterized in that the support film is composed of a resin composition which contains a thermofusible rein and a crosslinking agent, said thermofusible resin having a shearing stress at 180.degree. C. within a range of 9.times.10.sup.3 .times.1.times.10.sup.5 dyne/cm.sup.2, and which can form a non-fusible crosslinked resin having a shearing stress at 180.degree. C. of at least 1.times.10.sup.6 dyne/cm.sup.2 after the crosslinkage.
