The ratio of the binder of pigment is preferably shorter than 10:1, particularly less than 5:1.According to the selection of the depth-width ratio of pigment, its end to end
The setting of the longest dimension and the ratio between pigment/binder in portion, the color and reflecting that adjustable printing layer is observed in transmission
Middle observation color (such as be in transmission blue and be silver color, gold, bronze colour, coppery or purple in reflection；?
It can be purple, carmetta, pink colour, green or brown and the ratio between presentation and pigment/binder in reflection in transmission
The relevant different colours of selection).With between reflection and transmission (in other words, reflection light observation and transmitted ray
Between observation) gold/Blue transformation color for example in the example of the table of WO2011/064162A2 11,2 and 3
It mentions.In addition, example 4 shows the color converted with gold/purple, example 5 is shown with green-gold/fuchsin colour change
Color, example 7 shows the color with the transformation of purple/green and example 8 shows and becomes with silver color/impermeable light color
