Pre-coated plated steel sheet and molded product

A pre-coated plated steel sheet, comprising:

• a plating layer composed of Zn—Al—Mg-based alloy plating, the plating layer positioned on one side or both sides of a steel sheet;
• a chemical treatment film layer positioned on the plating layer;
• and
• a paint film layer positioned on the chemical treatment film, wherein:
• the paint film layer includes a primer paint film layer, and an upper paint film layer positioned on the primer paint film layer;
• and
• out of conditions below, at least any of the following is satisfied:
• both a condition (a-1) and a condition (a-2);
• a condition (b);
• and a condition (c),
• (a-1) a cut strength measured by cutting an interface between the paint film layer and a layer positioned on the steel sheet side relative to the paint film layer by a SAICAS method is 1.00 KN/m or more on average, 5% or less of a cut area is in the form of interfacial peeling, and the remaining cut area is in the form of cohesive failure within the paint film layer,
• (a-2) a cut strength of a portion measured by cutting an interface between the paint film layer and a layer positioned on the steel sheet side relative to the paint film layer by a SAICAS method is 1.00 KN/m or more on average, 20% or less of a cut area is in the form of interfacial peeling, and the remaining cut area is in the form of cohesive failure within the paint film layer, wherein the portion is where a thickness of the pre-coated plated steel sheet after being subjected to uniaxial elongation has decreased by 20% or more when compared to a thickness of a non-molded portion,
• (b) an indentation load when a microhardness measuring quadrangular pyramid-shaped indenter is inserted at a rate of 2 μm per minute with respect to a position 1 μm away in a direction of the primer paint film layer from an interface between the primer paint film layer and a layer positioned on the steel sheet side relative to the primer paint film layer, at a cross section obtained by cutting the primer paint film layer in a thickness direction, and the indenter reaches a depth of 10 μm, is less than 1000 mN,
• (c) a load curve with respect to a displacement when a microhardness measuring quadrangular pyramid-shaped indenter is inserted at a rate of 10 μm per second to a depth of 10 μm with respect to a position 1 μm away in a direction of the primer paint film layer from an interface between the primer paint film layer and a layer positioned on the steel sheet side relative to the primer paint film layer, at a cross section obtained by cutting the primer paint film layer in the thickness direction, and then the indenter is unloaded at a rate of 2 μm per minute is drawn, and at a plane defined by the displacement and the load, an area of a range surrounded by a straight line corresponding to the displacement of 10 μm, a straight line corresponding to the load of 0, and the load curve when performing the unloading is less than 500 μm·mN.
