Finish for touching surfaces

I had success with oil base urethane from a spray can directly on the acrylic paint, just remember several light coats is better than a heavy application.

Blocking is the property of paint you are describing - the sticking of paint to something that touches it (i.e acrylic wall paint used for bookshelves).
Using a harder acrylic formulation, such as an enamel paint , might help.

Tinted lacquer may also be a good choice.

I know those a close-up shots, but I think thinner coats would help as well, especially on the hinges.

Does the paint peel off in other areas or just around the hinges? It may be that the surfaces come together more tightly around the hinges. You could try putting a shim under the hinges to slightly increase the space between the lid and the box when you close it up.

The box has to close tightly, and yes, unfortunately, that's what's causing the problem. But keeping the opening wider is not an option.
Thank you!

Stop using the acrylic paint and consider something else or leave it natural. Why does it have to be painted to begin with?

It has to be painted. I don't know what else I can use. I've only ever worked with acrylics.

I use acrylics. When I finish I usually brush on a water based varnish. I have done decorative painting. The water based varnish does not tint the light colors. Poly does.

You've got to work with what you've already done. The finish is sticking to itself because when the lid is closed the pressure makes one surface stick to the other, and there's some residual tackiness still in the finish. You can't feel it, but it's there.
Here's a simple fix:
  • Touch-up paint all the areas where the finish has pulled off.
  • Let it dry at least 3 days, even go so far as to put a hot light bulb about a foot away.
  • Rub on paste wax with your fingertip; wipe off excess. You're not going for a wax polish; you just want the two surfaces to not stick to each other.

I sprayed the paint with Fixatif, but it's not enough. The paint peels off. What can I use on top of the paint to avoid peeling? The surface is wood and metal hinges.
Krylon Fixatif is mostly toluene and acetone, both of which act like paint stripper on your acrylic paint. Don't use it! I don't understand why the box has to be painted, particularly with acrylic paint.

The box picture that you sent looks like pine wood so why paint it?

A better picture of the entire box would be helpful to understand your idea behind the design. Is it your particular design element?
