Abstract

1. Una lámina retrorreflectante, que comprende una primera y segunda capas transparentes, una monocapa de microesferas transparentes empotradas en la primera capa en una profundidad media de menos de la mitad de su diámetro pero superior a una décima parte de su diámetro, estando los bordes extremos de las porciones de las microesferas que sobresalen de la primera capa alineados en un plano sustancialmente común, y estando estratificada la segunda capa transparente en contacto sustancialmente completo con la superficie cubierta de microesferas de la primera capa, con lo que está en contacto con las microesferas que sobresalen de la primera capa entre las microesferas, y se adapta y sigue las superficies curvas de las mismas, y una capa de reflexión especular aplicada como recubrimiento sobre la superficie configurada descubierta de la segunda capa. 2. Una lámina retrorreflectante según la reivindicación 1, en la que las microesferas cubren menos del 75 por ciento de la superficie de la primera capa polímera. 3. Una lámina retrorreflectante según las reivindicaciones 1 ó 2, en la que las microesferas tienen un diámetro comprendido en un intervalo igual a al menos alrededor del 50 por ciento del diámetro medio de las microesferas. 4. Una lámina retrorreflectante según las reivindicaciones 1, 2 ó 3, en la que al menos una de la primera y segunda capas comprende un polímetro termoplástico que tiene una reducción inferior a un orden de magnitud en el módulo de pérdida medio en dinas por centímetro cuadrado en una intervalo de temperatura de 50 grados dentro del interbalo de reblandecimiento del polímero. 5. Una lámina retrorreflectante que comprende una primera y segunda capas transparentes, una monocapa de microesferas transparentes empotradas en la primera capa en una profundidad de menos de la mitad de su diámetro pero más de una décima parte de su diámetro, cubriendo dichas microesferas menos de alrededor del 75 por ciento de la superficie estratificada, en contacto sustancialmente completo, con la superficie cubierta de microesferas de la primera capa, con lo que ésta en contacto con las microesferas que sobresalen de la primera capa, y se adapta y sigue sus superficies curvas, y también está en contacto con las porciones de la primera capa entre las microesferas, y una capa de reflexión especular aplicada como recubrimiento sobre la superficie configurada descubierta de la segunda capa. 6. Una lámina retrorreflectante según la reivindicación 5, en la que los bordes extremos de las porciones de las microesferas que sobresalen de la primera capa están alineadas en un plano sustancialmente común. 7. Una lámina retrorreflectante según la reivindicaciones 5 ó 6, en la que las microesferas tienen un diámetro que varía en un intervalo igual o al menos el 50 por ciento del diámetro medio de las microesferas. 8. Una lámina retrorreflectante según cualquiera de las reivindicaciones de 5 a 7, en la que al menos una de la primera y segunda capas comprende un polímetrotermoplástico que tiene una reducción menor de un orden de magnitud en el módulo de pérdida en un intervalo de temperatura del 50 grados, dentro del intervalo de reblandecimiento del polímero. 9. Una lámina retrorreflectante que comprende una primera y una segunda capas transparentes, una monocapa de microesferas transparentes empotradas en la primera capa hasta un profundidad media de menos de la mitad de su diámetro, pero mayor de una décima parte de su diámetro, estando la segunda capa transparentes estratificada, en contacto sustancialmente completo con la superficie cubierta de microesferas de la primera capa, con lo que está en contacto con los porciones de la primera capa entre las microesferas, y una capa de reflexión especular aplicada como recubrimiento sobre la superficie configurada descubierta de la segunda capa, variando el diámetro de dichas microesferas en un intervalo igual a al menos alrededor de 50 por ciento del diámetro medio delas microesferas. 10. Una lámina retrorreflectante según la reivindicación 9, en la que los bordes extremos de las porciones de las microesferas que sobresalen de la primera capa están alineados en un plano sustancialmente común. 11. Una lámina retrorreflectante según las reivindicaciones 9 ó 10, en la que las microesferas cubren menos de alrededor del 75 por ciento de la superficie de la primera capa. 12. Una lámina retrorreflectante según cualquiera de las reivindicaciones 9-11, en la que al menos una de la primera y segunda capas comprende un polímetro termoplástico que muestra una reducción menor que un orden de magnitud del módulo de pérdida en un intervalo de temperatura de 50 grados, dentro del intervalo de reblandecimiento del polímero. 13. Una lámina retrorreflectante.
