1) Three acrylic resin paints containing gold light red (c.i. pigment red 21), phthalocyanine blue (c.i. pigment blue 15), permanent orange HSL (c.i. pigment orange 36), respectively, were prepared. The three prepared acrylic acid coatings are respectively coated on the surfaces of three different aluminum alloy plates and cured. And respectively coating the finishing paints of examples 1-5 and comparative examples 1-4 on different areas of the surface of each aluminum alloy plate, and curing.
2) And (3) aging test: and (4) carrying out an aging test by adopting an ultraviolet artificial climate aging test box.
The test results are shown in table 1.
Table 1, organic pigment fade resistance test comparison.
As can be seen from Table 1, the UV-absorbing overprint varnish prepared by the present invention can effectively delay the fading time of organic pigments.

In the present invention, the term "prepared from" \8230 ", is used synonymously with" comprising ". The terms "comprises," "comprising," "includes," "including," "has," "having," "contains" or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
In the present invention, when an equivalent, concentration, or other value or parameter is expressed as a range, preferred range, or as a range defined by a list of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when the range "1 to 5" is disclosed, the described range should be interpreted to include the ranges "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like. When a range of values is described herein, unless otherwise specified, the range is intended to include the endpoints thereof, and all integers and fractions within the range.
In addition, the indefinite articles "a" and "an" preceding an element or component of the invention are intended to have no limitation on the number (i.e., number of occurrences) of the element or component. Thus, "a" or "an" should be read to include one or at least one, and the singular form of an element or component also includes the plural unless the number clearly indicates the singular.
