Layer sequence with colour flop effect including platelet-shaped effect pigments

A system comprising:

• a) at least one first colour layer (18) containing a dye (26) and/or pigment,
• b) on the at least one first colour layer (18) an effect layer (20) containing at least one platelet-shaped effect pigment (28),
• c) on the effect layer (20) at least one second colour layer (22) containing a dye (30) and/or pigment,
• wherein each of the at least one first colour layer (18) and of the at least one second colour layer (22) contains a dye (26, 30) and/or pigment being no effect pigment, wherein the at least one dye (26) and/or at least one pigment included in the at least one first colour layer (18) is different from the at least one dye (30) and/or at least one pigment included in the at least one second colour layer (22),
• wherein, at least if the at least one first colour layer (18) has a sum of reflectance and scattering of less than 40%, the system further comprises:
• d) below the at least one first colour layer (18) a lower layer (16) containing a pigment (24) and having a sum of reflectance and scattering of at least 40%,
• wherein:
• 1) the delta L of the system is at least 10, wherein the delta L is determined according to the equation delta L=|L[15°]−L[110°]|, wherein L[15°] is the L-value measured at an observation value of 15° and L[110°] is the L-value measured at an observation value of 110°, wherein the measurement is performed by irradiating in a dark environment a standardized light type onto the system at an angle of incident of 45° with respect to the horizontal direction, wherein the angle of reflection of 135° with respect to the horizontal direction is defined as an observation angle of 0°,
• and/or
• 2) the delta h° of the system is at least 15, wherein the delta h° is determined according to the equation delta h°=|h°[15°]−h°[110°]|, wherein h°[15°] is the h°-value measured at an observation value of 15° and h°[110°] is the h°-value measured at an observation value of 110°, wherein the measurement is performed by irradiating in a dark environment a standardized light type onto the system at an angle of incident of 45° with respect to the horizontal direction, wherein the angle of reflection of 135° with respect to the horizontal direction is defined as an observation angle of 0°,
• wherein the system does not contain any interference pigment, wherein the interference pigment is defined to be a pigment which produces an interference of light waves, and
• wherein the at least one platelet-shaped effect pigment (28) is composed of particles (46) having an average length (48) of 2 to 500 μm, an average width (50) of 2 to 500 μm and an average thickness of at most 1 μm.
