-as shown in Fig. 1, by tiny glass ball type retroreflection sheet, light is during from sealer 1 side incident; arrive the light L of glass bead 4 after glass bead 4 refractions; reflection on specular layer 7, and then once refraction on glass bead 4, and from sealer 1 side outgoing.At this moment light L is by the direction outgoing to intimate identical with incident direction.Light L carries out reflex reflection by this way.This reflex reflection light L because do not reflect, so not affected by the color of dyed layer 5 on dyed layer 5.And incide tiny glass ball type retroreflection sheet with light L from same direction, and the light L ' that arrives dyed layer 5 reflects on dyed layer 5.The light of this reflection only comprises the light in dyed layer 5 reflection wavelength band territories in light L '.Because dyed layer 5 is coccoid, light L ' carries out diffuse reflection on the surface of dyed layer 5, and its diffusing light is from sealer 1 outgoing.So, little to the light of light L ' incident direction reflection in the middle of light light L '.
In the time irradiating without the light of colored lights to tiny glass ball type retroreflection sheet night, getting back to major part in the reflection ray of light is reflex reflection light, and the light of getting back to light after dyed layer 5 reflections is only a few.So the reflection ray of getting back to light is subject to the impact of dyed layer 5 hardly.As long as sealer 1, holding sheet 3, any one in the middle of focus formation layer 6 do not have painted, are almost colourless light.
Tiny glass ball type retroreflection sheet will have from the light of various different directions incidents by day.Therefore,, while observing tiny glass ball type retroreflection sheet daytime, observer can be subject to the more light reflecting from dyed layer 5.The light that specular layer 7 reflects is the light in the reflection wavelength band territory of dyed layer 5.So, as long as sealer 1, holding sheet 3, any one in the middle of focus formation layer 6 do not have painted, and observer can be considered as the color of tiny glass ball type retroreflection sheet the color of dyed layer 5.
Because be not unfavorable for the resin of colour developing in the middle of dyed layer 5, and only formed by coccoid, so compared with situation about being made up of resin with dyed layer 5, the colour rendering of tiny glass ball type retroreflection sheet of the present invention is more excellent.Therefore, observing the tiny glass ball type retroreflection sheet that the personnel of retroreflection sheet see daytime is the darker retroreflection sheet of color.
In addition, tiny glass ball type retroreflection sheet of the present invention is only made up of coccoid because of dyed layer 5, and not resinous in the middle of dyed layer 5, so the position of the coccoid in the middle of dyed layer 5 easily changes.Therefore, dyed layer 5 self can Free Transform.On the other hand, fixed by tiny glass ball 4 because holding sheet 3 and focus form layer 6, interfix by tiny glass ball 4 so holding sheet 3 and focus form layer 6.Because the dyed layer 5 between holding sheet 3 and focus formation layer 6 can be out of shape, holding sheet 3 and focus formation layer 6 interfix simultaneously, so tiny glass ball type retroreflection sheet of the present invention can, in keeping integraty, have good pliability as a thin slice entirety.
The manufacturing process of tiny glass ball type retroreflection sheet:
First in the one side of sealer 1, print as required printed layers 2.Then in the one side of sealer 1, (with the one side of joining of printed layers 2) smears the holding sheet 3 of semi-harden state.Secondly, on holding sheet 3, put multiple glass beads 4.Thus, a part for glass bead 4 will enter in holding sheet 3 by surface tension effects.The degree that these glass beads 4 enter in holding sheet 3 can be adjusted by the hardening state that regulates holding sheet 3.Then make holding sheet 3 harden completely, when glass bead 4 is clipped in holding sheet 3, holding sheet 3 is fixed on sealer 1.Next step becomes the coccoid of dyed layer 5 under spreading on the holding sheet 3 of clamping glass bead 4.At this moment coccoid not only can drop on holding sheet 3, also can drop on tiny glass ball 4.At this moment can take gently coccoid with bristle etc., the viscosity ratio holding sheet 3 that also can roll on coccoid is clamped the little Dust adhering roller with small viscosity of strength of tiny glass ball.Because glass bead 4 is exposed at outside holding sheet 3, there is the Dust adhering roller of small viscosity by rolling, can only the coccoid on glass bead 4 be adsorbed onto on Dust adhering roller, and only between glass bead 4, leave coccoid.Next is put focus and forms layer 6, then lays out specular layer 7.Afterwards, coated with adhesive layer 8, then protection sheet 9 is attached on adhesive phase 8.
